Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP
address, you do not know in advance what your IP address is, and the address can change
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 (suc

DNS service does not work because private addresses are not routed on the Internet.
Your router contains a client that can connect to the Dyna

DynDNS.org. First visit their website at http://www.dyndns.org and obtain an account and
host name that you configure in the router. Then, whenever your ISP-assigned IP address
changes, your router automatically contacts the Dynamic DNS service provider, logs in to
