1	Introduction
--------------------

APNIC (the Asia Pacific Network Information Centre) is the Regional
Internet Registry for the Asia Pacific region, responsible
for distributing public Internet address space and related resources
in the region and for coordinating the development and implementation
of policies to manage those resources.

The policies described in this document have been developed by the
Internet community of the Asia Pacific region through a consensus
process facilitated by APNIC. They are to be implemented by APNIC and
by the National Internet Registries and the Local Internet Registries
throughout the region. 



2	Scope
-------------

This document describes policies for the responsible management of
global IPv4 public address space in the Asia Pacific region.
Specifically, this document focuses on the goals, assumptions, and
policies relating to the allocation and assignment of IPv4 address
space. 

This document does not describe specific addressing policies related to
IPv6, Multicast, Private Address Space, or Autonomous System numbers.
It should be read in conjunction with other APNIC documents, including
those dealing with membership and fees.



3	Hierarchy of IPv4 address space distribution
----------------------------------------------------

IPv4 addresses are distributed in accordance with the hierarchical
structure described in RFC2050, represented simply in fig.1.

In this hierarchy, IANA allocates address space to APNIC, to be
redistributed throughout the Asia Pacific region. APNIC allocates
address space to Internet Registries (IRs) and also delegates to them
the authority to make assignments and allocations. In some cases APNIC
assigns address space to end users. National and Local IRs allocate
and assign address space to their members and customers under the
guidance of APNIC and in accordance with the policies and procedures
described in this document.



4	Definitions
-------------------

The following terms and definitions are used in this document.


4.1	Internet Registry (IR)

	An Internet Registry (IR) is an organisation that is
	responsible for distributing IP address space to its members
	or customers and for registering those distributions. IRs are
	classified according to their primary function and territorial
	scope within the hierarchical structure depicted in fig.1
	above.

	IRs include: 

	* APNIC and other Regional Internet Registries (RIRs);
	* National Internet Registries (NIRs);
	* Local Internet Registries (LIRs), unless the specific
	  context of the reference requires otherwise.

4.1.1 	Regional Internet Registry (RIR)

	Regional Internet Registries (RIRs) are established under the
	authority of IANA to serve and represent large geographical
	regions. Their primary role is to manage, distribute, and
	register public Internet address space within their respective
	regions. Currently, there are four RIRs: APNIC, RIPE NCC, 
	LACNIC and ARIN, although a small number of additional RIRs 
	may be established in the future.

4.1.2	National Internet Registry (NIR)

	A National Internet Registry (NIR) primarily allocates address
	space to its members or constituents, which are generally LIRs
	organised at a national level. NIRs are expected to apply their
	policies and procedures fairly and equitably to all members of
	their constituency.

	The policies in this document apply to NIRs; however, this
	document does not describe the entire roles and
	responsibilities of NIRs with respect to their formal
	relationship with APNIC. Such roles and responsibilities may
	be described in other documents and agreements, subject to
	APNIC Document review procedures.

4.1.3	Local Internet Registry (LIR)

	A Local Internet Registry (LIR) is generally an Internet
	Service Provider (ISP), and may assign address space to its own
	network infrastructure and to users of its network services. 
	LIR customers may be other "downstream" ISPs, which further
	assign address space to their own customers. 


4.2	Internet Exchange Point

	An Internet Exchange Point (IX or IXP) is a layer 1 and layer
	2 network structure that interconnects three or more 
	Autonomous Systems (AS) for the purpose of Internet traffic
	interchange.


4.3	Address space

	In this document, address space means public IPv4 address
	ranges, excluding multicast addresses and private addresses
	defined by RFC1918.


4.4	Allocated and Assigned address space

	For the purposes of understanding APNIC address space policies,
	it is important to make a clear distinction between the terms
	"allocated" and "assigned".

4.4.1	Allocated

	Allocated address space is address space that is distributed
	to IRs or other organisations for the purpose of subsequent
	distribution by them.

4.4.2	Assigned

	Assigned address space is address space that is delegated to
	an ISP or end-user, for specific use within the Internet
	infrastructure they operate.

	Assignments must only be made for specific, documented purposes
	and may not be sub-assigned.



5	Goals of address space management
-----------------------------------------

5.1	Goals

	The goals described here were formulated by the Internet
	community and reflect the mutual interest of all members of
	that community in ensuring that the Internet is able to
	function and grow to the maximum extent possible.

	It is APNIC's primary duty, as a custodian of a public
	resource, to ensure that these goals are met within the Asia
	Pacific region. APNIC does this by providing guidance and
	leadership in developing and implementing responsible policies
	and practices.

	It is the responsibility of every NIR and LIR to also ensure
	that these goals are met within their respective regions and
	communities.

5.1.1 	Uniqueness

	Every assignment and allocation of address space must be
	guaranteed as globally unique. This is an absolute
	requirement for ensuring that every public host on the
	Internet can be uniquely identified.

5.1.2	Registration

	Assignments and allocations of address space must be
	registered in a publicly accessible registry. This is
	necessary to ensure uniqueness and to provide information for
	Internet troubleshooting at all levels. It also reflects the
	expectation of the Internet community that custodians of
	these public resources should be identifiable.

5.1.3	Aggregation

	Wherever possible, address space should be distributed in a
	hierarchical manner, according to the topology of network
	infrastructure. This is necessary to permit the aggregation
	of routing information by ISPs, and to limit the expansion
	of Internet routing tables.

5.1.4	Conservation

	To maximize the lifetime of the available resource, address
	space must be distributed according to actual need and for
	immediate use. Stockpiling address space and maintaining
	reservations are contrary to this goal.

	Conservation also implies efficiency. Therefore, all users of
	address space should adopt techniques such as Variable Length
	Subnet Masking (VLSM) and appropriate technologies that
	ensure the address space is not used wastefully.

5.1.5	Fairness

	All policies and practices relating to the use of address
	space should apply fairly and equitably to all existing and
	potential members of the Internet community, regardless of
	their location, nationality, size, or any other factor.


5.2 	Conflict of goals

	The goals of conservation and aggregation often conflict with
	each other. Also, some or all of the goals may occasionally
	conflict with the interests of individual IRs or end-users. 
	Therefore, IRs evaluating requests for address space must
	carefully analyse all relevant considerations and try to
	balance the needs of the requestor with the needs of the
	Internet community as a whole. 

	This document is intended to help IRs perform their role in
	consistent and equitable ways. IRs must maintain full
	documentation of and transparency within the decision making
	process.



6	Policy environment
--------------------------

Apart from the goals described in Section 5, other factors influence
the APNIC policy environment. These other factors include the
expectations of the Internet community, current administrative
structures, and technological constraints. 

The policy environment may change quickly or in unpredictable ways,
so APNIC, on behalf of its members, must monitor any changes and
communicate any policy implications. 

This Section describes the factors in the current operating
environment that have been most important in determining current
APNIC policies.


6.1	Routability 

	The routability of address space throughout the Internet can
	never be guaranteed by any single organisation.To reduce the
	number of globally advertised routes, ISPs may implement
	route filtering policies based on prefix length. As a result,
	small portable assignments are the most likely to suffer
	routability problems. Therefore, APNIC policies encourage
	those seeking address space to request from upstream
	providers rather than from APNIC directly.


6.2 	Internet growth rates

	Early strategies for distributing address space did not
	anticipate the rapid growth of the Internet and the scaling
	problems that followed, affecting both the amount of address
	space available and routing. Therefore, APNIC policies take
	account of past experience and seek to manage address space
	in a way that will maximise future scaling of the Internet.


6.3	Collective responsibility

	APNIC shares with its members and their customers a
	collective responsibility to ensure manageable and scalable
	Internet growth and to make decisions consistent with the
	goals described in Section 5. Therefore, APNIC policies and
	procedures are developed by APNIC members and the broader
	Internet community as a whole, in the common interest of
	those communities.  

	In implementing policies, APNIC and its members rely on an
	implicit trust that delegated responsibilities are carried out
	in good faith. Specifically, APNIC must trust that the
	information gathered from members during the request process
	is genuine and accurate.


6.4	Impartiality

	APNIC represents the interests of the Internet community in
	general and the Internet community of the Asia Pacific region
	in particular. Therefore, APNIC must apply its policies fairly
	and equitably, without regard to an organisation's size,
	geographic location, or any other factor.


6.5	Varying levels of expertise

	Different IRs and end users have varying levels of experience
	and expertise. APNIC policies allow for varying levels of
	assistance and monitoring, appropriate to ensure a consistent
	approach to address space management throughout the AP
	Internet community.


6.6	Address ownership

	The Internet community regards address space as a scarce,
	public resource that should only be distributed according to
	demonstrated need. ISPs and other organisations and
	individuals  that use address space are considered
	"custodians" rather than "owners" of the resource. As address
	space becomes more scarce, address space management policies
	may be adjusted by the community.


6.7	Address stockpiling 

	Stockpiling addresses is harmful to the goals of conservation
	and fairness. APNIC policies must prevent stockpiling and
	ensure efficient deployment of address space on the basis of
	immediate demonstrated need.


6.8	Evaluations to be based on best practice

	APNIC should ensure that address space holders adopt current
	best practice in management of the resources they use. If
	appropriate technologies exist for improved management of
	address space in particular situations, the community expects
	that those technologies should be used. 

	APNIC consults with its members and the broader Internet
	community to define and develop current best practice
	recommendations relating to Internet addressing technologies
	and techniques.


6.9	Private address space

	The use of private address space may be appropriate for
	addressing networks that are connected to the Internet via a
	firewall, and where there are not technical requirements for
	the use of public address space. 

	In general, private address space should be used for networks
	not connected to the Internet.


6.10	Minimum practical allocations

	Because the goals of aggregation and conservation conflict,
	it is necessary to apply a minimum practical size for address
	space allocations. This minimum allocation size may be
	reviewed from time to time, as technologies and	administrative
	conditions evolve. 

	The current minimum practical allocation is a /20 (4,096
	addresses).


6.11	Documentation

	To properly evaluate requests, IRs must carefully examine all
	relevant documentation relating to the networks in question.
	This documentation may include:

	* network engineering plans; 
	* subnetting plans;
	* descriptions of network topology;
	* descriptions of network routing plans;
	* equipment invoices and purchase orders;
	* other relevant documents.

	All documentation should conform to a consistent standard and
	any estimates and predictions that are documented must be
	realistic and justifiable.


6.12	Confidentiality

	The documentation which supports address space requests
	involves information that may be highly confidential to the
	organisations and individuals involved. Therefore, APNIC will
	operate in ways that reflect the trust implicit in its
	position by applying and enforcing procedures that protect the
	confidential information of its members and their customers.
	




Part 2:  Policies for address space management
_____________________________________________________________________



7	General policy framework
--------------------------------


7.1	IRs to adopt consistent address space management policies

	All NIRs and LIRs that receive address space from APNIC
	(either directly or indirectly) must adopt allocation and
	assignment policies that are consistent with the policies
	described in this document.

	NIRs and LIRs must ensure that address space for which they
	are responsible is only allocated or assigned subject to
	agreements consistent with the license provisions of section
	9.1.

	Also, NIRs must, wherever possible, apply slow start,
	assignment window, and second opinion policies to their own
	members in a manner consistent with the way APNIC applies such
	policies.



8 	Address requests
------------------------

8.1	Processing of requests dependent on correct documentation

	APNIC will only process requests that have been completely
	and properly documented. If the documentation contains errors
	or omissions, APNIC will advise the applicant as soon as
	possible. APNIC may also request the applicant to provide
	further information or clarify relevant issues that are not
	clear in the initial request.

	APNIC will process the request as soon as the errors and
	omissions have been rectified or the additional questions
	have been answered.

	APNIC will make all reasonable efforts to maintain a	
	consistent and reliable level of service with respect to
	processing of requests.


8.2	Security and confidentiality

	APNIC will maintain systems and practices that protect the
	confidentiality of all information relating to the commercial
	and infrastructure operations of all members and their
	customers. APNIC will ensure that the employment of all of its
	staff or agents is based upon an explicit condition of
	confidentiality regarding such information.

	APNIC provides for authorisation and verification mechanisms
	within the APNIC Whois Database. It is the responsibility of
	each IR	or end-user to apply these mechanisms.


8.3	Equitable processing of requests

	APNIC will deal with all requests strictly in the order in
	which it receives the proper documentation. To provide fair
	treatment for all applicants, APNIC will not in any
	circumstance provide for special treatment or make exceptions
	to the standard order of request processing.

	APNIC will seek to process all requests within a consistent
	time and will maintain a request tracking system for efficient
	request management.


8.4	General requirements for allocation requests

	All requests for address space must be supported by
	 documentation describing:

	* the network infrastructure of the organisation making the
	  request;
	* any address space currently held by that organisation;
	* previous assignments made by that organisation; and 
	* the intended use for the address space requested. 

	In addition to this general requirement, more specific
	documentation may also be requested (see Sections 9.2, 9.3,
	and 9.4).


8.5	Organisations seeking address space from multiple IRs

	Organisations must obtain their address space from only one
	IR at a time. Organisations requesting address space from any
	IR must declare all the address space they currently hold,
	regardless of the source. Organisations making concurrent
	requests to more than one IR must declare the details of all
	of those requests.

	In certain circumstances (for example, where an organisation
	is multihomed), strong technical reasons may justify an
	organisation receiving address space from more than one
	source.

	For the purposes of this section, a parent organisation and
	its subsidiaries are considered to be a single organisation.
	Exceptions may arise in cases where the parts of the
	organisation:

	* are separate legal entities;
	* maintain fully independent network infrastructures and are
	  routed under different Autonomous System numbers; or
	* or can otherwise demonstrate a justified need to obtain
	  address space from more than one IR.



9	Address allocation
--------------------------

9.1	Address space license

	APNIC will allocate and assign Internet resources on a
	'license' basis, with such licenses to be of specific limited
	duration (normally one year).

	The conditions of all licenses are described in the APNIC
	membership agreements, service agreements, and other relevant
	APNIC documents. 

	Licenses to organisations shall be renewable on the following
	conditions:

	* the original basis of the allocation or assignment remains
	  valid; and
	* that address space is properly registered at the time of
	  renewal.

	When a license is renewed, the new license will be subject to
	address space policies and license conditions effective at
	the time of renewal, provided that a minimum notice period of
	one year is given of any substantial changes to the conditions
	of the current license.

	All substantial changes to license conditions are subject to
	the consensus of APNIC members, in accordance with the APNIC
	Document Review Policies and Procedures.

	Individual licenses shall only be subject to review if the
	relevant IR has reason to believe that the existing license
	terms are no longer being complied with. IRs may implement
	their own procedures for the review of existing licenses as
	they see fit.


9.2	Slow start mechanism
 
	Subject to Section 9.2.1, APNIC and NIRs apply a slow start
	mechanism to all new LIRs. The slow start is applied to
	prevent allocations of large blocks of address space that may
	then remain substantially unassigned.

	The initial allocation an LIR receives from APNIC will be the
	size of the minimum practical allocation described in Section
	6.10.

9.2.1 	Exceptions to slow start

	In exceptional circumstances, an LIR may receive a greater
	initial allocation if it can demonstrate that its immediate
	need for address space exceeds the standard slow start
	allocation.

	The documentation required to justify an exception to the slow
	start may include (but is not limited to):

	* receipts for purchase of equipment,
	* purchase orders, or 
	* signed project contracts indicating the immediate network
	  requirements to be met by the LIR.


9.3	Criteria for initial allocation

	To be eligible to obtain an initial allocation, an LIR must:

	* have used a /22 from their upstream provider or demonstrate
	  an immediate need for a /22;
	* have complied with applicable policies in managing all
	  address space previously allocated to it; 
	* demonstrate a detailed plan for use of a /21 within a year;
	  and
	* commit to renumber from previously deployed space into the
	  new address space within one year.


9.4	Criteria for subsequent allocations

	After the initial allocation to an LIR, all subsequent
	allocations will depend on the following:

	* the LIR's verified usage rate (which is the rate at which
	  the LIR made assignments and sub-allocations from relevant
	  past allocations);
	* their documented plans for address space; and 
	* their degree of compliance with APNIC policies with respect
	  to relevant past allocations. 

	Based on these factors, APNIC and NIRs will allocate enough
	address space to meet the LIR's estimated  needs for
	a period up to one year. If APNIC or the NIR make an
	allocation based on a period of less than one year, then they
	must inform the LIR of the length of the period and the
	reasons for selecting it.

9.4.1	No guarantee of contiguous allocations

	APNIC will attempt to make subsequent allocations contiguous
	with previous allocations, but cannot guarantee that this will
	possible.


9.5	Prior allocations to be used first

	An LIR is not eligible to receive subsequent allocations until
	its current assignments account for at least eighty percent of
	the total address space from all allocations it holds. This is
	referred to as the "eighty percent rule".

9.5.1	Special circumstances - large assignments

	An LIR may request an exception to the eighty percent rule if
	it needs to make a single assignment that is larger than the
	amount of space remaining. 


9.6	Reservations not supported

	When an LIR wants to assign address space for customers, it
	must make the assignments from any address space it currently
	holds. 

	When evaluating allocation requests, reserved address space is
	considered to be unassigned.


9.7 	Address aggregation

	It is a condition of all allocations, that the allocated
	address space is aggregated by the LIR within a minimum 
	number of route announcements (preferably one).
	
	LIRs must only assign or sub-allocation addresses to
	customers who will be using those addresses in relation to
	network connectivity services provided by the LIR. 

	LIRs are expected to enter into agreements with their
	customers specifying that the end-user will hold the 
	addresses only for so long as the end-user remains a customer
	of that	LIR. Such agreements should also be consistent with the
	licence under which the address space is being used by the
        LIR.


9.8 	Validity of allocations and assignments

	An allocation or assignment of address space is valid only
	while the original criteria on which the allocation or
	assignment was based continue to be valid. 

	An allocation or assignment becomes invalid if it is:

	* made for a specific purpose that no longer exists; or
	* based on information that is later found to be false or
	  incomplete.

	If an allocation or assignment shall become invalid then the
	address space must be returned to the appropriate IR.


9.9	Transfer of address space

	Subject to the more specific provisions of Section 12, APNIC
	does not recognise the sale or unauthorised transfer of
	address space and will consider all such transfers to be
	invalid. APNIC will require organisations holding such
	transfers to return them to the appropriate IR.
 


10 	LIR address space management
------------------------------------

Subject to the following provisions, LIRs may either sub-allocate or
assign address space to their customers.

10.1 	Assignment window for LIRs

	APNIC and NIRs shall apply an assignment window mechanism to
	help LIRs understand and comply with APNIC policies and the
	address management goals.

	The assignment window indicates the maximum number of
	addresses that an LIR may assign or sub-allocate to an
	end-user without first seeking a 'second opinion'. If an LIR
	wishes to make an ssignment or sub-allocation that exceeds
	its assignment window, the LIR must first submit a second
	opinion request.
	
	LIRs start with an assignment window of zero, meaning all
	proposed assignments must first be approved. 

	APNIC or the relevant NIR will regularly assess the
	proficiency of LIR staff in making assignments and 
	sub-allocations and seeking second opinions, and will review
	the size of the assignment window accordingly. As the LIR 
	staff become more proficient, the size of their assignment
	window may be raised.

	The maximum assignment window given to any LIR will be a /19
	(8,192 addresses).

	If an LIR's staff appears to become less proficient (for
	example, due to the training of new staff or other relevant
	circumstances) then that LIR's assignment window may be
	temporarily reduced.


10.2	Assignment usage estimates

	Requests for assignments must be supported by usage estimates
	based on immediate and projected future need. These requests
	must be accompanied by documentation that supports the
	estimates.

	The estimates should made for the following periods:

	* immediately;
	* within one year; and
	* within two years.

	APNIC recommends that, as a general guideline, organisations
	should base their assignment requests on the assumption that
	25 percent of the address space will be used immediately and
	50 percent used within one year.

	The end-user must provide documentation that supports its one
	year usage estimate. If it is not possible for the end-user to
	estimate confidently what the two year usage rate will be,
	then APNIC or the NIR may make an allocation that will be
	sufficient for the one year needs only.


10.3	Sub-allocations by LIRs

	LIRs may sub-allocate address space to their downstream
	customers which are operating networks, such as ISPs, subject
	to the following conditions:
	
	* Sub-allocations are non-portable and must be returned to
	  the LIR if the downstream customer ceases to receive 
	  connectivity from the LIR.
	* Sub-allocations are subject to the LIR's assignment window.
	  Requests for sub-allocations which exceed the LIR's 
	  assignment window must first be referred to APNIC for 
	  second opinion approval.
	* The downstream customer which receives a sub-allocation
	  from an LIR is not permitted o further sub-allocate the
	  address space.
	  
10.3.1	Effect of sub-allocations on lIR's usage rate

	For the purposes of evaluating the LIR's usage rate (see
	sections 9.4 and 9.5), sub-allocated address space will be 
	considered as "used". However, APNIC will give careful
	consideration to the registration of assignments within the
	allocations, and may request supporting documentation as
	necessary.
	

10.4	Registration requirements

	IRs are responsible for promptly and accurately registering
	their allocations, sub-allocations, and assignments in the
	APNIC Whois Database, as follows:

	* All allocations and sub-allocations must be registered.
	* Assignments for networks greater than /30 must be
	  registered.
	* Assignments for networks of /30 or less may be registered,
	  at the discretion of the IR and the network administrator.
	* Assignments to hosts may be registered, at the discretion
	  of the IR and the end-user.
	  
10.4.1 Updating registration details

	IRs must update the APNIC Whois Database when any of the
	registration information changes. This is the responsibility
	of the IR concerned, but may be formally delegated to the end-
	user as a condition of the original assignment.

10.4.2	Registering contact persons

	Administrative and technical contact persons must be
	registered.

	The registered administrative contact ('admin-c') must be
	someone who is physically located at the site of the network,
	subject to the following exceptions:

	* For residential networks or users, the IR's technical
	  contact may  be registered as admin-c.
	* For networks in exceptional circumstances that make it
	  impractical to maintain an on-site administrative contact,
	  an off-site person may be registered as the admin-c.

	The technical contact ('tech-c') need not be physically
	located at the site of the network, but must be a person who
	is responsible for the day-to-day operation of the network.


10.5	Responsibility to maintain in-addr.arpa records

	LIRs should maintain in-addr.arpa resource records for their
	customers' networks. If a network is not specifically
	associated with an LIR then the in-addra.arpa records should
	be maintained by either the appropriate NIR or APNIC.



11 	Assignments and exchanges
---------------------------------

11.1	Small multihoming assignments

	An organisation is eligible to receive a portable assignment
	from APNIC if it:

	* is currently multihomed with provider-based addresses, or
	  demonstrates a plan to multihome within one month; and 
	* agrees to renumber out of previously assigned address space.
 
	An organisation is considered to be multihomed if its network
	receives full-time connectivity from more than one ISP and has
	one or more routing prefixes announced by at least two of its
	ISPs. 

	Organisations requesting a portable assignment under these
	terms must demonstrate that they are able to use 25 percent
	of the requested assignment immediately and 50 percent within
        one year.

	There is no minimum assignment size for portable assignments
        made under these terms.


11.2	Internet Exchange Points

	Internet Exchange Points are eligible to receive a portable
	assignment from APNIC to be used exclusively to connect the 
	IXP participant devices to the Exchange Point.
	
	The minimum assignment made under these terms is /24.
	
	Global routability of the portable assignment is left to the 
	discretion of the IXP and its participants.


11.3 	Critical infrastructure

	The following critical infrastructure networks, if operating
	in the Asia Pacific region, are eligible to receive a
	portable assignment:

	* root domain name system (DNS) server;
	* global top level domain (gTLD) nameservers;
	* country code TLD (ccTLDs) nameservers;
	* IANA;
	* Regional Internet Registry (RIRs); and
	* National Internet Registry (NIRs).

	Assignments to critical infrastructure are available only to
	the actual operators of the network infrastructure performing
	such functions. Registrar organisations which do not actually 
	host the network housing the registry infrastructure, will
	not be eligible for an assignment under this policy.

	The minimum assignment made under these terms is /24.

	Exchanges made under this policy remain subject to the
	address space license policy.


11.4 	Renumbering to promote aggregation

	Organisations holding multiple non-aggregated portable address
	blocks may return them in exchange for a single, aggregated
	range, under what is referred to as the "No questions asked
	policy". This exchange may be requested without the
	requirement to document the efficiency of existing assignments
	and the usage rates. 

	Exchanges made under this policy remain subject to the address
	space license policy.



12 	Mergers, acquisitions, and takeovers of LIRs
----------------------------------------------------

12.1	Updating registration details

	If an LIR changes ownership (due to a merger, sale, or
	takeover), then the new entity must register any changes to
	its network usage and contact personnel. If the effect of the
	ownership change is that the LIR changes name, then the LIR
	must provide to APNIC relevant legal documentation supporting
	the name change.


12.2	Effect on membership agreement

	If an LIR changes ownership then the new entity should advise
	APNIC of the change. APNIC membership is not transferable from
	one entity to another; however, if the effect of the ownership
	change is that the LIR becomes a subsidiary of another entity,
	and the infrastructures of the respective entities remain
	fully independent, then the membership agreement may continue.


12.3	Consequences for allocations

	Following ownership change of an LIR, APNIC will review the
	status of any allocations that are held by the new entity or
 	entities, with regard to the practical effect on their
	infrastructures.

	If the practical effect of ownership change is that the
	infrastructures are merged, then APNIC will not continue to
	make separate allocations to both. This situation will
	invalidate the membership agreement of the LIR that is
	effectively subsumed.

	When assessing the status of allocations, APNIC requires full
	disclosure of all address space held by all of the entities in
	question. If full disclosure is not made, then APNIC will
	consider any allocations to be invalid and will require that
	they be returned.


12.4	Closure of LIRs

	If an LIR holding APNIC address space ceases to provide
	Internet connectivity services, all of its address space must
	be returned to APNIC. It is the responsibility of the LIR (or
	any liquidator or administrator appointed to wind up the
	member's business) to advise all of its customers that address
	space will be returned to APNIC, and that renumbering into new
	address space will be necessary. 

	In the case that a new LIR takes over the business or
	infrastructure of the closed LIR, the existing address space
	may be transferred to the new LIR, however such a transfer is
	subject to reexamination by APNIC and may be treated as a new
	address request process.



13	Request evaluation guidelines
-------------------------------------

	This document does not provide specific details of request
	evaluation by APNIC, or of expectations relating to specific
	technologies. Such details are dependent on technological
	advances, and may change frequently. Therefore APNIC will
	publish separate guidelines documents relating to specific
	technologies or techniques as required.

	Such guidelines may contain any of  the following:

	* descriptions of evaluation procedures to be used for
	  certain types of address space requests;
	* summaries of the best current practices that organisations
	  requesting address space will generally be expected to
	  implement in their network plans; and
	* other information that may assist organisations to request
	  address space.

	Any guidelines published will be developed within the APNIC
	community, and will be consistent with the goals and policies
	described in this document.
