Great to know.. but what about cable routers??
Authored by: russh on May 18, '02 12:03:59AM

Hope this helps:

Here's how it works...

The Cable/DSL router "becomes" your computer insofar as the cable connection is concerned. Your cable modem delivers a DHCP addy to the router. The router then assigns addresses to your computers.. whether PC, MAC, Linux.... whether wired ethernet or through Wi-Fi Airport. You can tell the router to do this either through DHCP or through static ip. (It's all setup through your web browser.)

So your PC/Mac/whatever no longer worries what the cable modem is doing.. the connection is coming from the router. The router gets it's DHCP addy from the cable modem. (This arrangement adds a nice layer of security as well.)

You get an account with dyndns.org (Or another such service) and register your current DHCP addy and your qualified domain name (e.g. "mydomain.com") with them. dyndns.org offers software that runs in OS X (or 9) that watches your DHCP addy for changes. When it changes it alert dyndns.org and the address is updated automagically.

To wrap up, let me say that this all seemed very confusing to me until I finally took the plunge and bought a Linksys Cable/DSL router. Once I did I had my entire network running in literally 10 minutes and had the whole dyndns thing worked out in a couple days. (It only took that long because it takes a while for your address your propagate through the domain name servers on the net.

It's all sounds harder and more complicated than it is in practice.
