APNIC Member Meeting Seoul, Korea, 3 March 2000APNIC Open Address policy MeetingDiscussion Paper: Implementation of allocations from Network 61Problem definitionShould APNIC make allocations from network 61.0.0.0 on a regular basis as part of its total address pool? 1. MotivationAs the amount of traditional 'class C' space available for allocation diminishes, there is an increasing need to use space from other address blocks, such as the former 'class A' space. Current combined usage rates by the Regional Registries indicate that the remaining C space could be exhausted in just over two years. However, while only 21.9% (seven /8s) of the C space is available for allocation, 62.7% (79 /8s) remains available in the A space. 2. BackgroundIn April 1997, IANA allocated each Regional Registry a /8 from the A space. APNIC received 61/8. At the APNIC Member Meeting in June 1997, it was agreed that APNIC would allocate from 61/8 on a trial basis. Terms of the trial were that an allocation could be received in addition to an existing allocation from C space. The trial ran until December 1999. (Due to lack of resources, APNIC did not actively promote this trial.) The trial was similar to that of the RIPE NCC, for which the following conditions applied for class A allocations from 62/8:
The period of trial was April 1997 to December 1997. There was an option to return the whole range if it was not desired. 3. Current status (including other RIRs)APNIC ARIN In September 1999, ARIN made a public announcement describing their intention to make allocations from 64/8 as part of their total address pool. The smallest allocation to be made will be a /20 - the minimum allocation that ARIN currently makes. RIPE NCC Additional supporting statistics and graphs are available at [add url to diagrams] 4. DiscussionFeedback was sought from the APNIC member which participated in the trial and received an allocation in 1997. The member reported some problems relating to classful filtering by some ISPs. These problems were overcome by contacting the individual ISPs and requesting them to modify their filters. At that time, old classful equipment was also a problem at a few customer sites, but was overcome by upgrading either software or hardware. More recent feedback has indicated no subsequent problems. The only feedback received from ARIN members about 63/8 was in terms of ISP filters, but it should be noted that this was in 1997. ARIN posted their intention to make allocations from 64/8 to a number of mailing lists, including NANOG. To date, no negative feedback has been received. 5. RecommendationsBased on the feedback from the RIPE NCC and from ARIN, together with the APNIC members over the last two years since, it is recommended that:
