Appendix E: 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 domai n must be regi stered with Interni c via registratio n 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 h ave dialup, DSL or c able modem Internet conn ection where your
computer's I P addre ss chang es all th e time!! DDNS service su pports all top level domai n
names including but not limited to .com, .net, .org, .to, .uk etc.
2. Ethernet Network Environment
Normally, DDNS se rvice is only ne cessary for the users that could only obt ain dynami c IP
addresses. As to the u sers that co uld obtain the static valid IP address, they do not u sually
have to appl y the DDNS servi ce. Before we d ecide if DDNS is n ecessary for the users, we
have to check what kin d of Ethernet network enviro nment we have to inst all our Net worked
Device on.
(1) Environment of Fixed Valid IP Network
If users co uld obtain valid IP addresses, they c ould save the ef fort to apply DDNS se rvice.
Because the IP address i n this environment i s fixed, use rs coul d input th e 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.
