Dynamic DNS
If your ISP assigned you a fixed IP address, you can register a domain name and link it to
your IP address by public DNS. However, most Internet accounts use dynamically assigned
IP addresses that 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 (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 modem router contains a client that can connect to the Dynamic DNS service provided
by DynDNS.org. First visit their website at http://www
.dyndns.org and obtain an account and
host name that you configure in the modem router. Then, whenever your ISP-assigned IP
address changes, your modem router 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 modem router at http://hostname.dyndns.org.
