3.8.5 DDNS
Dynamic Domain Name System (DDNS) is a mechanism that can map a pre-defined domain name to
a dynamic IP address (updating DNS server with the dynamically assigned IP address). This is useful
when IP address for WAN interface is assigned dynamically.
If DDNS is enabled, clients can connect to CPE through “DDNS Host Name”.
