There is "ipv6only" parameter of the "listen" directive, which
allows to listen on ipv6 and ipv4 sockets reliably and
simulteniously regardless of the system configuration.
Configuration like

listen 80;
listen [::]:80 ipv6only=on;

will do the trick.

As of nginx 1.3.x, the ipv6only=on is used by default and there is
no need to specify it explicitly.

See http://nginx.org/r/listen for more details.
