IPv6 devotes a giant chunk of space to ephemeral link-local connections, if I recall correctly, at least a /64. So you'd need about 10^18 nanobots or so before you start to have to worry about link local address exhaustion.

These do not have to be globally unique, just unique on the local network.

Official assignments are at:

* https://www.iana.org/assignments/ipv6-address-space/ipv6-add...

Currently all public addresses are being assigned out of 2000::/3. The following are reserved for future (public?) use: 4000::/3, 6000::/3, 8000::/3, a000::/3, c000::/3.

Everything that starts with "f" is a special case, so the vast (vast) majority of address space is cleaved off.
