RFC 1467       Status of CIDR Deployment in the Internet     August 1993


   order to ensure the continued stable operation of the Internet.
   Recognizing the need for the mid-term mechanisms and receiving
   support from the Internet community, the US Federal Agencies proposed
   procedures to assist the deployment of these mid-term mechanisms.
   These procedures were originally described in RFC 1366 [1], which was
   recently made obsolete by RFC 1466 [2].  In October 1992, a schedule
   was proposed for the implementation of the procedures, described in
   RFC 1367 [3].

2. Milestones that have been met

   Most of the milestones of the proposed schedule were implemented on
   time. These milestones are shown below, essentially as they appear in
   [3], but with further comment where appropriate:

      1) 31 October 92:

         The following address allocation procedures were continued:

         a) Initial set of criteria for selecting regional address
            registries were put into place, and requests from
            prospective regional registries were accepted by the
            IANA.

            The Reseaux IP Europeens Network Coordination Centre
            (RIPE NCC) requested to become a regional registry.
            As per the addressing plan of RFC 1366, the RIPE NCC
            was given the block 194.0.0.0 to 195.255.255.255 to
            administer for the European Internet community. The RIPE
            NCC had previously and independently obtained the block
            193.0.0.0 to 193.255.255.255. Although this block had been
            allocated before RFC 1366, the RIPE NCC was able to manage
            it according to the guidelines in RFC 1366.

         b) Class A network numbers were put on reserve for possible
            future use. The unreserved Class A numbers became very
            difficult to obtain.

         c) Class B network numbers were issued only when
            reasonably justified.  Whenever possible, a block of C's
            was issued rather than a B. The requirements for
            allocating a Class B became progressively more constrained
            until the date in step (3).
