22.2.1  Procedure to Configure Dynamic DNS
Note: If you have a private WAN IP address, then you cannot use Dynamic DNS
To configure Dynamic DNS, go to Menu 1 — General Setup and select Yes in the Edit 
Dynamic DNS
 field. Press [ENTER] to display Menu 1.1— Configure Dynamic DNS as 
shown next.

Third System DNS 
Server
DNS (Domain Name System) is for mapping a domain name to its corresponding 
IP address and vice versa. The DNS server is extremely important because 
without it, you must know the IP address of a machine before you can access it. 
The Prestige uses a system DNS server (in the order you specify here) to resolve 
domain names for DDNS and the time server.
Press [SPACE BAR] and then [ENTER] to select an option. Select From ISP if 
your ISP dynamically assigns DNS server information (and the Prestige's WAN IP 
address). The IP Address field below displays the (read-only) DNS server IP 
address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS 
server's IP address in the IP Address field. If you select User-Defined, but leave 
the IP address set to 0.0.0.0, User-Defined changes to None after you save your 
changes. If you set a second choice to User-Defined, and enter the same IP 
address, the second User-Defined changes to None after you save your 
changes.
Select None if you do not want to configure DNS servers. If you do not configure 
a system DNS server, you must use IP addresses when configuring DDNS and 
the time server.
Edit Dynamic DNS Press [SPACE BAR] and then [ENTER] to select Yes or No (default). Select Yes 
to configure Menu 1.1: Configure Dynamic DNS discussed next.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to 
save your configuration, or press [ESC] at any time to cancel.
