Dynamic DNS
Dynamic DNS (DDNS) is an Internet service that allows routers with dynamic
public IP addresses to be located by using Internet domain names. To use DDNS,
set up an account with a DDNS provider such as DynDNS.com or TZO.com.
When this feature is enabled, and you have an active account with a DDNS
provider, the Cisco RV220W notifies DDNS servers of changes in the WAN IP
address, so that any public services on your network can be accessed by using
the domain name.
