Site should not be accessed through IP

[blason]

Hi Guys,

I have my nginx box deployed as a reverse proxy serving almost more than 10
sites. But when I browse through 1 IP the first site configured gets
accessed. I dont want anyone to access the sites through IP, by using only
FQDN sites should be accesible.

So anyone trying to access the site using IP should recieve a host not found
or may be error like COnnection reset.

Can we do that in nginx?
