Currently
getPeerIdreturns the first PeerId in the multiaddr. For most addresses this is fine. However, if a node is using a relay as an entrypoint, such as nodes running AutoRelay, getPeerId returns the id of the relay and not the destination peer.For example the multiaddr,
/ip4/0.0.0.0/tcp/8080/p2p/QmRelay/p2p-circuit/p2p/QmTarget, indicates that the target peerQmTargetis dialable over the relay peerQmRelay. RunninggetPeerIdresolvesQmRelayinstead ofQmTarget. The last peer id in the address should always be the target peer.
