Appendix G: DDNS Application
1. Preface
If you have a Cable modem or xDSL, this is a great way to host your own Networked Device 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). Your domain name's dynamic IP address is automatically tracked by a DDNS server.
Host your own Networked Device 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 service is 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 Networked Device 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 is under an environment of dynamic IP network (Dial-up xDSL), they have to apply a domain
name in advance. Then apply DDNS service. Finally setup the necessary information of DDNS and
PPPoE of the Networked Device in order to let the outside administrator be able to access through
internet.
