Here is an example of a regex that will search a text file and return a list of all the dates and their corresponding IP's. Currently it won't run using Active Perl on Win2k. Here is the code: 
#!/usr/bin/perl -w
use strict;

my $hacklist = "hack.txt";


open HACK, $hacklist or die "Can't Open $hacklist";

my ($octet, $date);

while (<HACK>){
    $octet ||= $_ if /($hacklist =~ m~((\d{1,3}\.){3}\d{1,3})~)/;
    $date ||=$_ if /Date:/;
}

close HACK;

print $date;
print $octet;
