4-9 DDNS
“DDNS” is an acronym for Dynamic Domain Name Service. Whenever you set up the web
servers, mail servers, or sometimes ftp servers, you need “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 Address identify the location of each device connected to Internet. However, the
human brain does not easily remember this numbering system, so a system that allocate 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.
