Earthlink, I believe; DENTS has a module for doing this for reverse DNS.

I think it was called DENTS; there's a white paper on it, but it's pretty
rough to Google, as you might expect.

So far as I can see, they still use it; my sis is an EL cablemodem customer,
and her rDNS is algorithmically generated.
