It seems to me that options relating to IPv4 don't belong in RA/DHCPv6 -- they belong in DHCPv4. Having a degenerate DHCPv4 server that just NAKs every request would appear to solve all of the problems in Section 3. The main point is that having a dedicated DHCPv4-NAK-ing server avoids the need to configure all IPv6 routers with IPv4-related information -- a serious operational concern if you have many IPv6 routers on a single link. (To be fair, you might need a new DHCPv4 option that says "do not try to contact any other DHCPv4 servers" to solve your problems 3.1/3.2. But then, I'd like to see some operational experience that shows that it is a problem in practice.) -- Juliusz (who wishes people would stop dumping gazillions of unrelated options into existing protocols) _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
