I think any "No IPv4"-flag would need to be just a hint to the hosts, and it would only be relevant to the router actually sending that RA. So if your normal DHCPv4 "give up" time is X, then if this flag it set, shorten X to something much less? The IPv6 specs say M=1 is a hint that tells the host that it might use DHCPv6 to acquire addresses if it so wants, right? Nothing says it can't do IA_NA request if M=0, and nothing says a host does the wrong thing if it doesn't do IA_NA request? I think this flag should be the same level of hint, and then the rest is up to the host implementation to do what it think is best. -- Mikael Abrahamsson email: swmike@swm.pp.se
