Public DNS for hosts which have both AAAA and A records. www.kame.net, for example. >From an internal network as described (RFC1918 IPv4 addresses with global connectivity through NAT, site-local IPv6), this is what I used to get for such hosts: In Fedora Core 4, glibc would always return the IPv4 address first. In Fedora Core 5, glibc would return the unreachable IPv6 address first. In the pending update to FC5's glibc, the precedence table has been changed so that IPv4 addresses are _always_ favoured over IPv6. That means that even on hosts which _do_ have a global IPv6 address, it's going to give me the IPv4 address first and IPv6 is never going to get tested. I think that a better solution to 'fix' the current kernel+glibc would be for glibc's default RFC3484 table to contain a separate label for fec0::/16, so that in the above situation, the IPv4 destination address gets chosen by Rule 5. -- dwmw2 -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
