Apache virtualhost directive: only ServerName, nothing else -

if create vhost directive, catch requests on ip address. if set servername, other requests redirected documentroot of entry. how can drop requests except specific domain? e.g.:

virtualhost 46.108.122.78:80     servername mysite.com 

(i know can specify second directive without servername , redirect e.g. empty dir. however, want explicitly drop these requests.)

the first name-based virtualhost given ip:port default when no other servername/serveralias matches.
