dnsmax.pl is a Perl dynamic DNS update client for the DNS Max and ThatIP DNS services. It runs on Linux, FreeBSD, Mac OS X, and other operating systems with Perl support.
dnsmax.pl is responsible for keeping your DNS records pointed at your current IP address. When run, the program checks to see whether your IP address has changed since the last time an update was sent to the servers. If it has, the program sends an update. The program should be scheduled to run every few minutes.
Linux and Mac OS X
