My cable modem provider (Comcast) doesn't allow dyndns as part of their AUP. I think its so they can sell static IPs on their expensive work at home plan... :^(

Exsqueeze me? Comcast doesn't allow it? And how exactly do they police it? Doesn't the service work entirely externally, simply linking your current IP to an "dyndns.org" address of your choosing, all in their own online database?

(I ask so pointedly because I am a MediaOne/AT&T Broadband customer, in the process of being assimilated by Comcast.)

...and I use dyndns.org to maintain access to my calendar, contacts, photo album and more on the road! It works perfectly well for the home office, and I'm happy with how it works.

The day Comcast prevents me from using this third party's service (without offering a static IP at a comparable price) is the day I cancel my subscription with them. And move over to DSL!
