Hi, >>>>> On Thu, 10 Jan 2013 00:23:01 +0000 >>>>> Ben Morrow <ben@morrow.me.uk> said: ben> ip6addrctl does more than just order v4 vs v6: it also sorts the v6 ben> addresses, in a way which can be quite important.

Okay, it seems reasonable. I've just committed to obey ip6addrctl only for IPv6 address: http://svnweb.freebsd.org/changeset/base/245256 As for gethostbyname2, it doesn't obey ip6addrctl in the first place, and it is hard to obey ip6addrctl. So, I leave it as is. ben> Well, if important applications like Sendmail are still using it it's ben> probably important it works consistently with the rest of the system's ben> IPv6 support. I'd rather see it removed, or reimplemented as a wrapper ben> around getaddrinfo, than left in a broken state. I don't think our getipnodebyname is broken. We tried to implement getipnodebyname with getaddrinfo backend without success in years past. As the result, implementation of getipnodebyname has become like now.
