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.
