Detailed Description

Signature we use to verify that the broadcast was really made by the peer that claims to have made it.

Basically, affirms that the peer is really using this IP address (albeit possibly not in our LAN). Makes it difficult for peers in the LAN to claim to be just any global peer – an attacker must have at least shared a LAN with the peer they're pretending to be here.
