P2P

(1/1)

Botsareus:
I always thought that, in a P2P network, the software needs to upload its IP( or whatever) to a central server in order for others to see it and communicate. Is that so? Or, can this happen virtually without the need for any central server at all?

Peter:
You'll need the IP somehow to have P2P communication, most P2P also has some kind of a central server to regulate it.

Could use some kind of a DHT, though.

ikke:
You don't need a central server, you need to find one node in the network. A central, static entry is an easy way to implement
