 WAN IP address is needed when Virtual Server, DMZ Host, and Tenda App function are enabled. If the router’s 
WAN IP address changes, these functions will not in normal service. The DDNS function allows you to map a 
dynamic WAN IP address (public IP address) of the router to a static domain name, helping internet users (WAN 
side) access router by static domain name. 
 If you dislike remembering complex IP address, you can also enable the DDNS function. To access the 
configuration page, click Advanced Settings > DDNS.
