MAC and Identity

Your IP is just one identifier. Devices and browsers expose many others: MAC addresses, hostnames, browser fingerprints, and account logins. True anonymity means controlling all of them.

This lesson focuses on spoofing low-level identifiers, especially the MAC address, and understanding what else can give you away.

A MAC address is a 48-bit hardware identifier burned into a network interface, written as six hex pairs like a4:5e:60:1f:2c:8b.

The first three bytes are the OUI, identifying the manufacturer. MAC addresses operate at Layer 2 and are only visible on the local network segment, not across the internet.
