MAC Address Generator
Generate random MAC addresses with configurable separators, uppercase formatting, and vendor OUI lookup. Useful for network testing, spoofing simulations, and hardware address generation.
MAC Address Generation
MAC addresses are 48-bit hardware identifiers typically written as 12 hexadecimal digits. The first 24 bits (OUI) identify the manufacturer. This tool generates locally administered addresses by setting the second-least-significant bit of the first byte, avoiding conflicts with real vendor OUIs.
