Dear Colleagues,
At the IETF 78 Meeting in Maastricht in July 2010,
the Operations
and Management Area Working Group (OPSAWG) presented “IANA Reserved
IPv4 Prefix
for IPv6 Transition”. This presentation introduced the Internet draft
document that
specifies the use of a reserved IANA /8 address block from its
remaining pool
of unallocated IPv4 addresses.
"[...] IPv4 address space reserved for Service Provider or large
enterprise use with the purpose of facilitating IPv6 transition and
IPv4
coexistence deployment. This space SHOULD only be used for the purpose
of
providing NAT'ed IPv4 access to subscriber networks or IPv6-in-IPv4
tunnels
during the transition to full IPv6 deployment. These addresses MAY be
used
without any coordination with IANA or any other Internet registry. "
The Internet draft document is available at:

Discussion on this draft document is ongoing at:
