Emulator question: Is there an IP check at the Activation time?

I noticed a strange behavior during my emulator tests.
After activating an emulator, if I try to activate a second one on the same machine or on a PC in the same network, it not require the parameters but it directly takes the parameters of the first machine activated.

How does this procedure happen?
Is there an IP check?
How can I avoid it?

There are no IP checks on the emulator activation, you should be able to install multiple emulators on the same machine. We do it all the time and have not experienced any issues.
I am guessing this is happening due to the serial numbers being generated on the emulators, the serial number is tied to the business so if the same serial number is used this might happen.
Could you please share the OS and the version of android studio you are working on.
