This is concerning ipv6 autoconfiguration on a local segment where you don't have a router. From my understanding, the PCs assigns itself an IPv6 address (FE80...) and the PCs can communicate among them. So in order for a PC to communicate with another, it needs to know the other PC IPv6 address (FE80...). Correct?
If yes, then is there a way to discover those IPv6 addresses from a PC?
