and we replace these IP numbers to easy remember names, which are organized into
the domain name. As to ADSL environment, most of the users will use dynamic IP

dealer.
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 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 lookup domain names and translates them into IP
addresses. Domain names 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 or refer to
Appendix F for more information.
