3.3.4 DDNS
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
the application of this function, a domain name shall be applied for and registered on a proper
website such as www. 3322. org.
InRouter305 DDNS service types include QDNS (3322)-Dynamic, QDNS(3322)-Static,
DynDNS-Dynamic, DynDNS-Static, DynDNS-Custom and No-IP.com.
To set DDNS, click the "Service >> Dynamic Domain Name" menu in the navigation tree, then
enter “Dynamic Domain Name” interface.
