I've been wondering about the private_nets const in src/or/policies. It was added in a96c0affcb4cda1a2e0d83d123993d10efc6e396 but Nick doesn't remember why, and I'm hoping someone has an idea (maybe teor, who I've CCed here, who documented this in a later commit?). If nobody knows why we do this I think we should remove it as likely incorrect.
0000::/8 is Reserved by the IETF, it is (a superset of) the deprecated space for "IPv4 Compatible IPv6 Addresses". The addresses are not to be reassigned for any other purposes.

I'm not necessarily sure what private networks are all used for in Tor, but maybe this explains it and makes sense?
