Do you know about the WIMIP automation page? This could make your life much easier:

#! /usr/bin/perl

use strict;
use warnings;

my $oldip = '';

while (1){
    my$ip = `wget -q http://automation.whatismyip.com/n09230945.asp -O
+-`;
    my @t = localtime();
    $t[5] += 1900;
    my $date = $t[5] . '-' . $t[4] . '-' . $t[3] . ' ' . $t[2] . ':' .
+ $t[1];
    
    if ("$ip" ne "$oldip"){
        print "IP changed on $date from \"$oldip\" to \"$ip\"\n";
        $oldip = $ip;
    }
    else
    {
      print "IP unchanged on $date. Is: \"$ip\"\n";
    }
    sleep 15;
}
