Configure Dynamic DNS 
The Dynamic DNS client (DynDNS) updates DNS hostnames with the current IP address of a 
particular interface. Dynamic DNS operates under the specification supplied by DynDNS (go to 
http://dyn.com), referred to in the web interface as Dynamic DNS.
When an interface connects, the client checks the current IP address of that interface. If the IP 
address differs from that obtained from the previous connection, the Dynamic DNS service is 
contacted, and the hostnames specified in the Hostname parameters are updated with the new 
address.
