Biasing stupidly is the root of all evil. Stuart Cheshire explained how to make this work, and it's going to be a standard feature in MacOS 10.7, but there's no reason why we can't fix ssh now. Your syscall, or library call, should be saying "here's a name, give me a connection to it," not "what's the IP address of this name" and then "now make a connection to that IP address." Your argument boils down to saying that as apps become IPv6-capable, they should still prefer IPv4 if it's available. But that's just squandering an opportunity for win. The right thing to be doing is fixing applications so that they do the *right* thing, not fixing them so that they do something very much like what they were doing before, only with a different bias. The question of whether to break AAAA records is one small piece of this larger discussion, and if you make a choice here that prevents the right thing being done at the higher layer, that's a *really* bad outcome. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
