“DDNS” is an acronym for Dynamic Domain Name Service. Whenerver you set up
the web servers, mail servers, or sometimes ftp servers,you need a
the web servers, mail servers, or sometimes ftp servers,you need a
“Domain Name”
to help Internet users reach your servers easily.
Internet actually runs on IP Addresses which are
numerical order, for example
“66.37.215.53”. These IP Addresses identify the location of each device connected to
the Internet. However, the human brain does not easily remember this numbering
system, so a system that allocates a domain name such as “www.dyndns.org” provides
an easier method. If you type “66.37.215.53” or “www.dyndns.org” in the web
browser’s address bar, the browser will show the same web page. This is because both
methods relate to the same web server. The “Domain Name Servers” used to manage
the Internet will translate “www.dyndns.org” into the IP Address “66.37.215.53” in
order to allow your browser to find the web server and display the correct web page in
your browser.

If your “WAN Connection Type”, as shown in One Page Setup section, is “Obtain IP
Address Automatically”, “PPPoE”, or “PPTP” with dynamic IP address assigned by
ISP, it will cause an error when you set up the public computer servers in your LAN
side PCs. Internet users may not be able to reach your servers because your WAN side
IP address may change each time you initiate the connection to your ISP. The DDNS
function will help to map your IP address to your domain name when your ISP assigns
a new dynamic IP Address.
