  Is it?! I always thought that Docker uses 172.16.0.0/16 by default for its networks. Did that get changed at some point?

    That’s what the documentation says. I don’t know if/when that changed as I barely use docker.

      Well I’ll be damned, there’s a 192.168. tucked away at the end of the 172. ranges:

      docs.docker.com/engine/network/#automatic-subnet-…

      {
        "default-address-pools": [
          { "base": "172.17.0.0/16", "size": 16 },
          { "base": "172.18.0.0/16", "size": 16 },
          { "base": "172.19.0.0/16", "size": 16 },
          { "base": "172.20.0.0/14", "size": 16 },
          { "base": "172.24.0.0/14", "size": 16 },
          { "base": "172.28.0.0/14", "size": 16 },
          { "base": "192.168.0.0/16", "size": 20 }
        ]
      }

  It appears to be, but I didn’t know that until today. And beyond that, I’ve been trying every permutation of both that IP and the IP of the server on my network in my Jellyfin proxy settings, and it still hasn’t helped to surface the origin IP address.
