The Internet uses DNS servers to lookup domain names and translate them into IP addresses. Domain names, such as www.veo.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 and best of all they’re free to use. Two such services you can use are www.no-ip.com and www.DynDNS.org. You’ll need to register with the service and set up the domain name of your choice to begin using it. Please refer to the home page of 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. Please 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 webpage for further information and terms and conditions.
