5.6.6 DDNS
Dynamic Domain Name Service (DDNS) is a system for mapping a dynamic IP
address on a fixed DNS. When the DDNS is enabled, the router will associate its
dynamic WAN IP to a fixed domain name. Then, router services can be accessed
through the fixed domain name at any time, anywhere, without needing to track
the router's WAN IP.
