FWIW, Linode (where my sole server is hosted) gives me a /64 IPv6 block
for free. That's 2^64 addresses. And the same with our home ISP, in case
I felt like violating the terms and running a server.

I only use one of the Linode addresses for now; and I have not tested
how many reverse DNS records I can create, but I know it's more than one.
