Hi Bob, How is this different from https://tools.ietf.org/html/draft-ietf-sunset4-noipv4-01 ? Thanks, Simon 2017-11-17 1:42 GMT-05:00 Bob Hinden <bob.hinden@gmail.com>: > 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.
