Hi guys, after read this thread,
https://community.teamviewer.com/t5/TeamViewer-11/Check-and-Track-Incoming-Log-and-IP-Details/m-p/1514#M412
I still dont get what i need. im trying to figure it out, who are connected to my pc using teamviewer. I already check the logs "Incoming_Connection.txt" and "TeamViewer_13_Logfile.log", but i got nothing.
Then i try to search more till i found this,
https://www.systoolsgroup.com/forensics/teamviewer/
They said, the IP address are in "TeamViewerXX_Logfile.log". Again, im trying to tail my logs in that file, and try to connect using different connection. And still get nothing.
Can someone give me a direction to get the IP address? 
Thank You,
