4-13 DDNS
“DDNS”
is an acronym for Dynamic Domain Name Service. Whenerver 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.
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.
Note that this DDNS function acts as the client appliance of DDNS service and is only
able to be use 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
www.dyndns.org
for further information.
