Game keeps communicating with Unity3D

H there guys. Im just curious. I’ve noticed for my game a lot of communication is being done with Unity3D. I did make use of the unity master server at one point. So Im just wanting to make sure. Is this what Im seeing? Or is my game communicating with Unity for another reason?

09:49:26,4191795 game.exe 2676 UDP Send WIN-6CLDFSTRCFT.[redacted]:25000 → host6.unity3d.com:50005 SUCCESS Length: 32, seqnum: 0, connid: 0

There’s a lot of traffic for this.

The host6.unity3d.com part is odd because that DNS name does not exist afaikt. What IP address does it resolve to on your side? But the source port 25000 looks like the default builtin networking server port and 50005 is the default NAT facilitator port. So this looks like traffic which will occur if you use NAT punchthrough in the game or if you use the connection tester.
