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
- 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
- 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.
