         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.

RFC 1367        Schedule for IP Address Space Guidelines    October 1992


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.
