MAC Address Generator

Generate valid hex MAC addresses with optional OUI prefix

Separator

Letter case

Optional OUI prefix

How many

Create MAC address samples for networking tests and device fixture data.

Choose separator style, letter case, amount, and optionally provide an OUI prefix to keep vendor bytes fixed while randomizing remaining bytes.

The first bytes of a MAC address identify the vendor assignment block. Setting an OUI helps simulate realistic device pools.

Useful for QA data generation, network inventory demos, parser validation, and automation scripts requiring formatted hardware identifiers.
