I am a new user to SyncThing and I have greatly enjoyed the tool. I am utilizing it on two machines on my LAN. I regularly look at the network traffic in my home and I have noticed an excessive amount of DNS queries from SyncThing. Is this normal? Syncthing is producing over 20k DNS queries in the last 24 hours. In comparison, dropbox only produced 169 queries and it is installed on several machines.
Queries in the last 24 hours below (had to take off the last two letters to post)
Syncthing makes discovery https requests when looking for other devices. I think this is normal. It’s once a minute, but should be cached a bit by your local resolver. Not sure why you have ~3.7 requests per looking for the v6 servers though. Maybe the resolver is look for A records, CNAME records before hitting AAAA records? I don’t think it matters much to be honest.
Like I said, I don’t think it matters. There’s nothing out there that will be hurt by a DNS packet once a minute, even four of them. But you can change the reconnect interval if you like.
