Schedule for IP Address Space Management Guidelines

Status of this Memo

This memo provides information for the Internet community. It does

not specify an Internet standard. Distribution of this memo is

unlimited.

IntrodUCtion

This memo suggests a schedule for the implementation of the IP

network number allocation plan described in RFC1366. This schedule

is meant to support the implementation and deployment of an address

aggregation mechanism for the Internet by proposing an achievable

target for which we can all aim. The timely deployment of that

aggregation mechanism and the IP addressing plan will help the the

size of the Internet router forwarding tables and management of the

IP address space. By doing so, it will help the current Internet

addressing and routing technology operate during the interim period

until the next generation technology is deployed. This interim

solution in no way constrains the selection of the next generation

addressing and routing technology.

This draft schedule was put together by the FNC Engineering and

Planning Group (FEPG) based on the IP addressing plan BOF of the July

1992 IETF meeting, as well as discussions with a number (though, of

course, not all) of knowledgeable and interested parties, including

the IANA and IR. This draft schedule assumes that the address

aggregation mechanism will be available in the Internet by mid-1993.

The activities described in this schedule are the precursors to that

deployment, and will promote the efficient operation of that

mechanism. We feel that our assumptions are realistic and that this

schedule can be met. We encourage its open discussion as we move

toward community consensus.

Please send comments to topolcic@nri.reston.va.us, or to the

mailing list ipalloc@nri.reston.va.us. To be added to this

mailing list, send a request to ipalloc-request@nri.reston.va.us.

Note that the references below to an addressing plan and to criteria

for regional address registries refer to RFC1366.

Draft Implementation Schedule for IP Network Number Allocation Plan:

1) 31 October 92:

The following address allocation procedures are continued:

a) Initial set of criteria for selecting regional address

registries will be put into place, and requests from

prospective regional registries will be accepted by the

IANA.

b) Class A network numbers are practically impossible to

oBTain.

c) Class B network numbers will continue to be issued only when

reasonably justified. If possible, a block of C's will be

issued rather than a B. The requirements for allocating a

Class B will become progressively more constrained until the

date in step (3).

d) Class C network numbers will be allocated according to the

addressing plan. Allocation will be performed by the

Internet Registry (IR) if an appropriate regional registry

has not yet been designated by the IANA.

2) 14 February 93:

Re-evaluate and readjust the schedule if necessary.

3) 15 April 93:

a) The IR begins to allocate all networks according to the

addressing plan in appropriately sized blocks of Class C

numbers.

b) Class B network numbers will be difficult to obtain,

following the recommendation of the addressing plan and only

issued when justified.

4) 6 June 93:

EXPected date that an address aggregation mechanism is

available in the Internet.
