Hi, Brian and I took a cut a defining an IPv4 Availability Flag for IPv6 ND Router Advertisements. From the Introduction: Hosts that support IPv4 and IPv6, usually called dual stack hosts, need to work on IPv6 only networks. That is, a link where there are no IPv4 routers and/or IPv4 services. Monitoring of IPv6-only networks, for example at the IETF 100 meeting in Singapore, shows that current dual stack hosts will create local auto-configured IPv4 addresses and attempt to reach IPv4 services. A mechanism is needed to inform hosts that there is no IPv4 support and that they should turn off IPv4. Because there is no IPv4 support on these links, the only way to notify the dual stack hosts on the link is to use an IPv6 mechanism. An active notification will be much more robust than attempting to deduce this state by the lack of IPv4 responses or traffic. IPv4-only hosts, and dual-stack hosts that do not recognize the new flag, will continue to attempt IPv4 operations, in particular IPv4 discovery protocols typically sent as link-layer broadcasts. This legacy traffic cannot be prevented by any IPv6 mechanism. The value of the new flag is limited to dual-stack hosts that recognize it. We were originally thinking it would be an April 1 submission, but after reading the discussion on the IPv6 list, we decided it makes sense as a real submission :-) Please review and comment.
