That's why I switched to Dish when Time Warner took over Comcast.

Sure, but not all vendors will do this.

I suspect the simple way to view things is you need 3 layers

- physical connection
- tcp/ip protocol support
- applications support

The physical connection is cable, dsl, modem or whatever.

The tcp/ip protocol support is the part that allows your tcp/ip stack to
talk the the remote tcp/ip stacks and that understand the protocols such
as DNS, HTTP and so on.

The applications are the stuff that uses the lower layers to provide
services and content.

I know folks that buy their DSL circuits from the phone company and get
their ISP services from elsewhere.
