Sorry to bother again but I am kinda urgent on this so I am working this on my own but at the same time I hope i get more insights from professionals which can allow me to do it in a better way. My current script also searches for IP in a network range from all the log file. This is the code that does what I've mentioned: 
use Net::Subnet;

if (@ARGV){
        while (<>) {
        my @ips = m/(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(
+?:25
        +[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)/g;
        next unless @ips;
        next unless grep { $matcher->($_) } @ips;
        print $fh $_;
        }

Do you know how I can implement this into your code? Thanks again
