No, just a port means IPv4 wildcard address.

No, IPv6-and-IPv4 listen sockets will be created if and only if
you'll explicitly set the ipv6only parameter to off.

(Before nginx 1.3.4, the operation system setting was used as a
default for ipv6only. This was proven to be a wrong approach, and
now nginx forces ipv6only=on by default. See
http://nginx.org/r/listen for some more details.)
