Dynamic DNS Registration
Your Internet Service Provider (ISP) provides you with one IP address which you use to connect to
the Internet. The address you get may be static, meaning it never changes, or dynamic, meaning
it’s likely to change periodically. Just how often it changes depends on your ISP. A dynamic IP
address complicates remote access since you may not know what your current WAN IP address is
when you want to access your network over the Internet. The solution to the dynamic IP address
problem comes in the form of a dynamic DNS service.
The Internet uses DNS servers to look up domain names and translates them into IP addresses.
Domain names, such as www.intellinte-network.com, are just easy-to-remember aliases for IP
addresses. A dynamic DNS service is unique because it provides a means of updating your IP
address so that your listing will remain current when your IP address changes. There are several
excellent DDNS services available on the Internet. An excellent DDNS services is
www.DynDNS.org. You’ll need to register with the service and set up the domain name of your
choice to begin using it. Refer the home page or the service for detailed instructions.
A DDNS service works by uploading your WAN IP address to its servers periodically. Your
gateway-router may support DDNS directly, in which case you can enter your DDNS account
information into your router and it will update the DDNS servers automatically when your IP
address changes. Consult your router’s documentation for more information. If your router does
not support DDNS, you can run a small client utility on any PC on your network, which will perform
the updating. The client utility is usually provided for free by the service.
Check the service’s Web page for further information, terms and conditions.
