This script will update the A DNS record for a subdomain at NearlyFreeSpeech.NET with the public IP address for the machine the script runs on. Run this script on a server in which the public IP address is dynamic and changes so your subdomain is always up to date.

There are two steps to this script. First, it retrieves the configured IP address for the subdomain, the current public IP address of the server, and then compares the two. If the public IP address is different, it updates the A record of the subdomain with the new IP address.
