DDNS (Dynamic Domain Name Server)
The IP address (Ex. 210.168.0.22) is like a telephone number, while the website address
is like a name in an address book. The DDNS allows the user to access the website by
entering the name of the website without memorizing a bunch of cold numbers.
When you apply for an Internet service, you will have at least one IP address from your
ISP that is either fixed or dynamic. Most of the ADSL service providers will give you a
dynamic IP for ADSL environments, which means your IP address will constantly change
each time you connect to the Internet. As a result, users from WAN environments will
have much difficulty finding the correct IP address. The DDNS (Dynamic DNS service) is
created for exactly this kind of moment. By updating your WAN IP address each time you
connect to the Internet, the DDNS helps you locate your website and access your website
easily. You can find a lot of free DDNS service providers on the Internet, such as
www.no-ip.com and www.DynDNS.org .
Some gateway-routers can directly communicate with DDNS. In this case, you may
directly enter your DDNS account on the setting page in the Internet router, and then the
router will update your WAN IP status whenever it is changed and report to the DDNS. If
your router does not support direct communication with the DDNS, you can download a
small application program on the DDNS service page to help you update your WAN IP.
