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.

6man is the design authority for extensions and modifications to the IPv6
protocol. The working group may at its discretion, review any document
extending or modifying the protocol, carried out in another working
group, and may determine that 6man working group consensus is needed
before any of those documents can progress for publication.
