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, in consultation with the responsible AD, may recommend to the IESG that 6man working group consensus is needed before any of those documents can progress for publication.
