Can all peers see each others IP addresses? #54

Just wondering how secure/anonymous trystero is.

If I create a room and a number of users join, can they all see the IP addresses of the other people? And if so how easy is that to access?

jeremyckahn commented 11 months ago

AFAIK peer IP addresses are exposed to others via SDP strings. These strings are obtained from the pairing mechanism (WebTorrent/IPFS/Firebase) and used to locate and connect peers. I don't know that a WebRTC connection can be established without some sort of SDP string exchange.

Yes given that they're p2p connections a savvier user could use some network monitoring tools to view IP addresses but it's more complicated than simply opening up the browser dev inspector.
