If you set *:80 and do not set "bind" on listen's, then nginx will listen
on *:80 only, and will call getsockname() to learn address:

     server {
         listen  80;
         listen  192.168.1.1:80;
         ...
     }

     server {
         listen  192.168.1.2:80;
         ...
     }

     server {
         listen  192.168.1.3:80;
         ...
     }
