This memo   does not specify an Internet standard of any kind.  Distribution of   this memo is unlimited.Abstract   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.Statement   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   space.   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.IAB & IESG                   Informational                      [Page 1]

RFC 1881           IPv6 Address Allocation Management      December 1995   Any revenues (such as transaction fees) received with respect to the   IPv6 address space should be used only for expenses related to   registry activities, and not to subsidize any other activities.   There will be no charges for the address space itself, only fees to   recover the registry costs.   Any situation in the management of the IPv6 address space that leads   to monopoly control or predatory practices must be avoided.   The IANA will develop a plan for the initial IPv6 address allocation,   including a provision for the automatic allocation of IPv6 addresses   to holders of IPv4 addresses. IANA will also develop mediation and   appeals procedures concerning delegation and revocation.Security Considerations   Security issues are not discussed in this memo.Contact Information:   Internet Architecture Board   EMail: <iab@isi.edu>   Internet Engineering Steering Group   EMail: <iesg@cnri.reston.va.us>IAB & IESG                   Informational                      [Page 2]
