RIP, unless modified in a non-standards complaint way, cannot
provide IP addresses, only routing info. I guess it is possible
that it is a modified RIP protocol in use, and if that is the case
it would explain a lot.

Comcast uses the Quagga routing software suite for authenticated RIP, but it still requires that a Comcast tech log into your SMC gateway remotely and manually setup the static IP information.

Thank you! I suspected it was a policy decision that created
a technical limitation, and that it had nothing to do with the
assignment of the address.

It is still odd to me that they would choose to use a dynamic
routing protocol with a /30, instead of assigning their single
IP customers one address in a /24, but that would be a policy
decision, and I am sure it makes sense to the folks behind the
scenes.

I take this as good news, as policies change often and there
is at least a chance I can get what I want before my three
year contract is up.

The single IP address method is what I used to see with AT&T for my DSL circuits with a single IP address option. AT&T did it using their PPPoE authentication (which Comcast does not use). Comcast could do it using MAC address authentication (which is a standard feature in any DHCP service), but I suspect they don't want to get involved with keeping up with the hassle of having to manually update the DHCP server(s) every time a customer gets a new router, or PC, or changes a NIC. By limiting static IP assignments to a specific router that they supply, they eliminate a lot of maintenance headaches for their support people.

I guess AT&T spoiled me. I had a static plan with them on DSL
that pre-dated their PPPOE roll out. The setup call, no tech
required, was 'Here is your IP, gateway and netmask'. They
made a royal mess of my billing after 12 years, so I dropped
them for a CLEC that gave me almost the same setup.

That CLEC also had a killer account portal that allowed for fairly
involved changes to the service in near realtime. I could see
a similar setup that requested the user provide their device
MAC address and issue a random password for the RIPv2 update.
A business account that does not have access to an IT person
pays for a truck roll, and is someone does know what they are
doing can handle it themselves.

Heck, I have my one class-C. If they are actually doing dynamic
routing updates for my single usable leased, they should be happy
to let me bring my own address space (provided it passes the
ownership test). Sadly I doubt that is anymore likely at this
point.

My Linux router could happily run Quagga just fine! It's too bad they don't just give us the keys so we can run our own routers.
