Why not use public key as IP. Like yggdrasil-go, use `public_key.sha256.first_63_bit === ipv6[1..64]` (maybe some data error but here is how it works). Well, yggdrasil is an overlay network, it can do that. But the ISP network cann't. Maybe we all should move to an overlay network.

we can even add ipv8 ipv12 or ipv256 whatever, then `public_key.sha256 === ipv256`. So we can even have 0rtt in tls.
