How to Set Up a Cron Job on DD-WRT to Auto Update Your IP

By using a cronjob to visit your API url on a regular basis you can ensure that the IP in your Unlocator account is always up to date. Please see the examples of a couple of cronjob commands below.

# Hourly:

# Every 3 hours
0 */3 * * * root wget --post-data='api_key=Your_API_KEY_HERE' https://unlocator.com/tool/api.php
