Oh wow, I didn’t know they were still around! I used that to get an IPv6 address more than a decade ago; I think they used the bastardized IPv4-mapped-to-v6 address format at the time. But iirc it involved extra network hops because it was tunneled rather than routed, but maybe I’m misremembering.

I’m guessing they have larger blocks for sale?
