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 VPN, 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 VPN, DDNS and the time server.
