6.4 Configure Dynamic DNS
Note:
The Dynamic DNS function is only available in AP Router and AP Client Router (WISP
Client) Mode.
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. With Dynamic DNS function enabled, users can 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.
Register an account to DDNS service provider (NO-IP, Dyndns or Comexe) first.
