Hello!

Currently I have problem with upstream with IPv6. For example I have
an origin with subdomain dual-stack-ipv4-ipv6.xtremenitro.org.

dual-stack-ipv4-ipv6.xtremenitro.org IN A 192.168.1.1
dual-stack-ipv4-ipv6.xtremenitro.org IN AAAA 2001:xx:xx::1;

My configuration are like this :
$ nginx -V

I see on error log, all error was came from IPv6 upstream.
