3.4.2 DDNS Setup
“DDNS” is an acronym for Dynamic Domain Name Service. Whenever you set up
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 in numerical order, for example
“66.37.215.53”. These IP addresses identify the location of each device connected to
Internet. However, the human brain cannot easily remember this numbering system,
so a system that allocates 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 input
relate to the same web server. The
“Domain Name Server” 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” is “PPPoE” with dynamic IP address assigned by the
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.
Note that this DDNS function acts as the client appliance of DDNS service and is only
able to be used in conjunction with the service provided by DynDNS.org. Before you
begin using this function, you will need to apply to DynDNS.org to be able to use the
service. Please visit
