I just installed Syncthing on Linux and when I launch it in the command line, I notice various worry external IP addresses and wonder what they may be for?
I simply want to syncronize a local desktop with a local laptop and don’t see any reason to be connecting to anything outside of my local network.
The specific references are:
[DPIPJ] 19:39:23 INFO: Relay listener (dynamic+https://relays.syncthing.net/endpoint) starting

Is anyone able to put my mind at rest regarding these please?
