How to Trace an IP: What's the Best Method? or Can Someone Explain How to Trace an IP Properly?

Thanks for all the tips, guys! Tried Grabify like someone suggested, and it worked pretty well for a basic test.

Still confused about how VPNs mess with tracing tho—anyone got a dumbed-down explanation?

Also, is there a way to check if an IP is behind a VPN or just raw? Appreciate the help!
