Dynamic DNS allows a system administrator to associate a name with the system public address. When a change occurs to the system public interface, the Dynamic DNS service is notified of the change. Dynamic DNS is used in systems with frequently changing public addresses (DHCP or PPPoE). Even systems with static addresses can use dynamic DNS to assign a name to a system.

  1. Choose Network > Dynamic DNS.
