4.1.3 DDNS Service

DDNS: Stands for Dynamic Domain Name Server

Your Internet Service Provider (ISP) provides you at least 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 device over the Internet.

One of the possible solutions to the dynamic IP address problem comes in the form of a

dynamic DNS service.

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. One such service you can use

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. Please refer to the home page of the service for detailed

instructions or refer to Appendix G for more information.

If your device is connected to xDSL directly, you might need this feature. However, if your

device is behind a NAT router, you will not need to enable this feature because your NAT

router should take care of this job. As to xDSL environment, most of the users will use

dynamic IP addresses. If users want to set up a web or a FTP server, then the Dynamic

Domain Name Server is necessary.
