DDNS 12.6
12.6.1
Overview
DDNS is short for Dynamic Domain Name Server. It detects when your IP address changes and maps
your dynamic IP address to a static domain name. When the service is running, the DDNS client on
the router sends its current WAN port IP address to the DDNS server. Then the server updates the
mapping between the domain name and the IP address in the database to implement dynamic
domain name resolution. If you enable this function, the router sends its WAN IP address to the
specified DDNS server when the WAN IP address is changed and the DDNS server maps the changed
WAN IP address to a specified static domain name. This enables internet users to access services on
your LAN through the static domain name instead of the changeable WAN IP address.
This function always interworks with other functions, such as Port Forwarding, DMZ Host and
Remote Web Management.
Choose More > DDNS, and enable this function, the configuration page appears. See the following
