Make sure the remote system can send mail. Create a script in cron's hourly folder.

sudo -e /etc/cron.hourly/ipcheck

The contents of the file:

#!/usr/bin/env bash
wget -q -t 5 --output-document=- "http://automation.whatismyip.com/n09230945.asp" | mailx -s "External IP Address" me@mydomain.com

Set the script to executable:

sudo chmod 0755 /etc/cron.hourly/ipcheck

@david Um... sudo -e invokes the default editor that will create a new file (ipcheck) in the /etc/cron.hourly/ directory. It's a BASH shell script. –  user8290 Jan 3 '13 at 20:51

use crontab

 crontab -e

and then add below lines

 0 * * * * wget -q -t 5 -O - "http://automation.whatismyip.com/n09230945.asp"
