DDNS
The DDNS page allows you to make use of a DDNS server. Dynamic DNS (DDNS)
allows a dynamic IP address to be aliased to a static, pre-defined host name so that the
host can be easily contacted by other hosts on the internet even if its IP address
changes. This means you can host a server on your LAN that can be accessed from
anywhere on the Internet.
Caution:
Some service providers may consider connection of such a server to be a
breach of your service agreement.
The Cable Modem/Router supports a dynamic DNS client compatible with the Dynamic
