Record if the player connected to X ip

Hello, the video game has a client-side and server-side antihack.

Client side is handled by a .dll and communicates with the server.
On the server side there is a hackserver.exe

I have access to both codes.

Job:
There is a hack of the video game that is undetectable, but when you open it it communicates with the license (IP) so if we detect that the player connects to that (IP) we can send a record to the server.

Is this possible?

Thanks for your time
