Hrmmm, in light of this clarification, I think something like the following may be best ...

use Socket;
use URI;

my $url = 'http://www.mydomain.com';

my $uri = URI->new( $url );
my $ip_addr = gethostbyname( $uri->host );
$ip_addr = inet_ntoa( $ip_addr );

if ( $uri->host eq $ip_addr ) {

    #... Creatures evolve, code does stuff

}

The advantage that this method of employing the URI module over a simple regular expression is the correct handling of more complex URLs (which may incorporate username and password authentication details in the form of scheme://username:password@host:port/) and validation of IP addresses.

 

perl -e 'print+unpack("N",pack("B32","00000000000000000000000111001001")),"\n"'
