Appendix G: DDNS
Application
1. Preface
If you have a Cable modem, xDSL, ISDN or Dialup, this is a great way to host your
own Web Server, FTP Server, Mail Server, Video Server or other TCP/IP Service.
Get your own domain like www.yourname.com*, www.yourname.com.tw* etc. (Note:
This domain must be registered with Internic via registration authorities such as
Network Solutions, DirectNIC, Register.com etc). A DDNS server automatically
tracks your domain name’s dynamic IP address.
Host your own Web Server, FTP Server, Mail Server, Video Server and much
more no matter what your computer's IP address may be and even if you have dialup,
DSL or cable modem internet connection where your computer's IP address changes
all the time!! DDNS service supports all top level domain names including but not
limited to .com, .net, .org, .to, .uk etc.
2. Ethernet Network Environment
Normally, DDNS services are only necessary for the users that could only obtain
dynamic IP addresses. As to the users that could obtain the static valid IP address,
they do not usually have to apply the DDNS service. Before we decide if DDNS is
necessary for the users, we have to check what kind of Ethernet network
environment we have to install our video server or IP camera on.
(1) Environment of Fixed Valid IP Network
If users could obtain valid IP addresses, they could save the effort to apply DDNS
service. Because the IP address in this environment is fixed, users could input the
IP address or domain name of demo site directly in the IE browser.
(2) Environment of Dynamic IP Network
If users are under a environment of dynamic IP network (Dial-up ADSL), they have to
apply a domain name in advance. Then apply DDNS service. Finally setup the
necessary information of DDNS and PPPoE of the video server or IP camera in order
to let the outside administrator be able to access through Internet.
