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.
Service Provider Select your DDNS service provider fro
m the available DDNS service
providers including NO-IP (www.no-ip.com), Dyndns (www.dyndns.com)
and Comexe (www.comexe.net).
