The 6man working group is responsible for the maintenance, upkeep, and advancement of the IPv6 protocol specifications and addressing architecture. It is not chartered to develop major changes or additions to the IPv6 specifications. The working group will address protocol limitations/issues discovered during deployment and operation. It will also serve as a venue for discussing the proper location for working on IPv6-related issues within the IETF. The 6MAN WG will review all proposed extensions to IPv6 developed in other working groups to ensure that they are consistent with the IPv6 architecture and specifications. The working group's work items are as follows: - Resolve open issues with “U/G” bits in Interface Identifiers - Develop approach for IPv6 Fragmentation - Develop approaches for IPv6 Extension Headers (Hop-by-Hop and Destination) - Extensions/changes to core IPv6 protocols such as IPv6 Neighbor Discovery - New IPv6 over approaches if appropriate for 6MAN - Advance IPv6 core specifications to Internet standard All new work items not listed above require the approval of the working group and the sponsoring Area Director before they will be taken on by the working group.
