IPv6 Address Allocation Management
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
The IPv6 address space will be managed by the IANA for the good of
the Internet community, with advice from the IAB and the IESG, by
delegation to the regional registries.
The IPv6 address space must be managed for the good of the Internet
community. Good management requires at least a small element of
central authority over the delegation and allocation of the address
The Internet community recognizes the Internet Assigned Numbers
Authority (IANA) as the appropriate entity to have the responsibility
for the management of the IPv6 address space.
The IANA will rely on the advice of the Internet Architecture Board
(IAB) and the Internet Engineering Steering Group (IESG) in the
management of the IPv6 address space.
The IANA will delegate to regional (and other) registries the task of
making specific address allocations to network service providers and
other subregional registries. Individuals and organizations may
obtain address allocations directly from the appropriate regional (or
other) registry, or from their service provider.
Delegation of address space by the IANA is not irrevocable. If, in
the judgement of the IANA, a registry has seriously mishandled the
address space delegated to it, the IANA may revoke the delegation,
with due notice and with due consideration of the operational
implications. IANA will make every effort in such a case not to
revoke addresses that are in active use, unless there are
overwhelming technical reasons for doing so.
