Dear SIG members

Below is a summary of discussion on the proposal to date. We
encourage you to continue discussion on the mailing list before
APNIC 25.

Summary of discussion to date
-----------------------------

    - This proposal and the IPv6 ULA addresses concept are similar.

    - Networks in other regions are likely to want to use this shared
      space. How could APNIC restrict use of the shared use addresses
      to the Asia Pacific region?

        - If the addresses were to be used globally, then the proposal
          should perhaps be an IETF or IANA proposal.

    - There would be the same problem of address collisions in the
      proposed shared use addresses as there are  in RFC 1918
      addresses.

    - It is unlikely that 'Redesignation of 240/4 from "Future Use"
      to "Limited Use for Large Private Internets"' will happen as
      it would require major infrastructure changes.

    - Expanding private use addresses by designating one /8 as
      'shared use' would increase pressure on the remaining IPv4 free
      pool.

    - If global uniqueness in addressing is desirable, LIRs should
      help with the transition to IPv6.

    - This proposal only delays the point at which decision makers
      realise the situation is critical and results in a far smaller
      timeframe in which to transition to IPv6.
