3.2.8 DNS
DNA (Domain Name System) is a DDB used in TCP/IP application programs, providing switch
between domain name and IP address. Through DNS, user could directly use some meaningful
domain name which could be memorized easily and DNS Server in network could resolve the
domain name into correct IP address. The device makes analysis on dynamic domain name via
DNS.
Manually set the DNS, use DNS via dialing if it is empty. Generally, it needs to set this only when
using the static IP at the WAN port.
Click the “Network>>Domain Name Service” menu in the navigation tree to enter the “Domain
Name Service” interface.

3.2.9 Dynamic Domain Name
DDNS maps user's dynamic IP address to a fixed DNS service. When the user connects to the
network, the client program will pass the host’s dynamic IP address to the server program on the
service provider’s host through information passing. The server program is responsible for
providing DNS service and realizing dynamic DNS. It means that DDNS captures user's each
change of IP address and matches it with the domain name, so that other Internet users can
communicate through the domain name. What end customers have to remember is the domain
name assigned by the dynamic domain name registrar, regardless of how it is achieved.
DDNS serves as a client tool of DDNS and is required to coordinate with DDNS Server. Before
