ddclient - Update IP addresses at dynamic DNS services

       A perl based client to update your dynamic IP address at DynDNS.com (or other dynamic DNS services such
       as Hammernode, Zoneedit or EasyDNS), thus allowing you and others to use a fixed hostname
       (myhost.dyndns.org) to access your machine. This client supports both the dynamic and (near) static
       services, MX setting, and alternative host. It caches the address, and only attempts the update if the
       address actually changes.

       For usage information please run ddclient-help until this manpage is finished.
