Frequently Asked Questions
What is a MAC address?
A MAC address is a unique 48-bit hardware identifier for network interfaces, formatted as six hex pairs.
How to find my MAC?
Windows: ipconfig /all. Mac: System Preferences > Network > Advanced. Linux: ip link show.
Can MAC be spoofed?
Yes in software, but the original hardware MAC remains permanently burned into the adapter.
Can a MAC address be used to track my location?
MAC addresses are only visible on local networks and cannot be tracked across the internet. However, Wi-Fi probe requests with your MAC can be tracked in physical spaces. Modern devices use MAC randomization to prevent this.
What is the difference between a MAC address and an IP address?
A MAC address is a hardware identifier burned into your network adapter, used for local network communication. An IP address is a logical address assigned by the network for internet routing.
