- Request for Comments: 1367 CNRI
- October 1992
-
-
- 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 RFC 1366. 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.

-
-
- 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.
