How to distinguish between different devices with same IP?

Hi,
How to distinguish between different devices(applications) with the same IP address but different network port?

1. How to assign the different users to these two devices?
2. How to recognize which device is using DLNA media in Serviio Console? (If I play a video on TV, I can only find the play record in serviio.log)

I can see this in my Serviio Console status tab:

  Code:

192.168.1.3      Media Player Sharing      Generic DLNA profile   


But they have the same IP address but different network port in Device Spy:

  Code:

Devices on an IP network cannot have the same IP address and have both functioning. I can't explain what you're seeing, but most likely it's the same device with two different processes that are identifying themselves with different names on different ports.

Yes, you are right.
