Not only are bridges private, but they can also modify their network packets in a way that it’s difficult for an observer to conclude that somebody is using Tor - that’s when OBFS4 comes into play. However, thanks to bridges, Tor users can still connect to the network when the public Tor relays are blocked. One way to prevent people from using Tor is to block the public IP addresses of all thousands of Tor relays. In general, relays that make up the Tor network are publicly listed.
