How to bind nginx to ipv4 and ipv6 interface ?

[Lukas Tribus]

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

Remember that ipv6only is a socket option, and you can specify a socket option
only once per address:port pair:

So your config needs to look this way, if you have multiple server statements in your config:
> server {
> 	listen 80;
> 	listen [::]:80 ipv6only=on;
> 	[...]
> }
> server {
> 	listen 80;
> 	listen [::]:80;
> 	[...]
> }
> server {
> 	listen 80;
> 	listen [::]:80;
> 	[...]
> }
