ddclient

A Perl Client to Update Dynamic DNS Entries

ddclient is a client requiring only Perl. Supported features include daemon operation, manual and automatic updates, static and dynamic updates, optimized updates for multiple addresses, MX, wild cards, abuse avoidance, retry for failed updates, and status updates to syslog and through e-mail. ddclient can obtain the IP address from any interface, through a Web-based IP detection service, and for multiple routers using custom FW definitions. It also provides full support for DynDNS.org's NIC2 protocol. Support is also included for other dynamic DNS services. Comes with sample scripts for use with DHCP, PPP, and cron.
