4.2.2 DDNS
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.
