frequently. In this case, you can use a commercial Dynamic DNS service. This type of service
lets you register your domain to their IP address and forwards traffic directed at your domain
to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.
Your gateway contains a client that can connect to the Dynamic DNS service that is provided
by DynDNS.org. First visit their website at
host name that you configure in the gateway. Then, whenever your ISP-assigned IP address
changes, your gateway automatically contacts the Dynamic DNS service provider, logs in to
your account, and registers your new IP address. If your host name is hostname, for
example, you can reach your gateway at http://hostname.dyndns.org.
