The best way to store unique values is to use a hash.

You are sorting a single value, not a list of values.

I would do it something like this:
#!/usr/bin/perl
use warnings;
use strict;
use Socket;
my %IPs;
while ( <> ) {
$IPs{ inet_aton( $1 ) }++ if /\b(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\b/;
}
for ( sort keys %IPs ) {
print inet_ntoa( $_ ), "\n";
}
print "\nTotal IP'S = ", scalar keys %IPs, "\n";
