Chapter 7 Management Tab
Dynamic DNS
The main function of Dynamic DNS (DDNS) is mapping the fixed domain name to dynamic IP address.
When a device connects to the Internet through PPPoE or Dynamic IP, the WAN IP address it gets is not
fixed, which is inconvenient for the Internet users to access the servers in the local area network through IP
address. Dynamic DNS function allows users to access servers using a fixed domain name.
The DDNS server will establish a mapping table about the dynamic IP address and the fixed domain name.
When the WAN IP address of the device changes, it will make an update request to the specified DDNS
server, and then the DDNS server will update the mapping relation between the IP address and the
domain name. Therefore, whenever the WAN IP address changes, users on the Internet can still access the
servers in the local area network using a fixed, easy-to-remember domain name.
The DDNS function that serves as the client of DDNS service must work with DDNS server. Please register
an account to DDNS service provider (NO-IP, Dyndns or Comexe) before using this function.
