IP from keypair

(This post is a summary of a conversation within the Hyprspace Matrix room)

In Yggdrasil, nodes will generate an ipv6 address from their public key, this gives Yggdrasil nodes a few advantages:

1. The ip-addresses don't need to be manually set, and, it should be nearly impossible for these generated ip-addresses to clash with another nodes'.
2. The ip-addresses act as a form of verification, only the node with the keypair can generate that specific ip-address, so it's possible to trust a peer in the network solely by it's ip-address and not just by it's PeerID.

However, this is limited to ipv6 as ipv4's comparably small address space means clashing is unacceptably likely. Hyprspace can also use this ip-address scheme from Yggdrasil by generating an ipv6 address from the public key used for the PeerID, here's what it may look like:

interface:
  ...
  address: 10.1.1.1/24
  gen_address: true
  ...
