Network test-data utility

MAC Address Generator

Generate one to 100 cryptographically random unicast MAC addresses with local-bit and formatting controls.

Count (1–100)CaseSeparator

Locally administered bit

Unicast bit is always enforced.

Random bytes come from Web Crypto. These are synthetic addresses and are not vendor-assigned OUIs.

About MAC Address Generator

Create synthetic addresses for labs, fixtures and test data using browser cryptographic randomness.

Input is processed locally in your browser and is not sent to Navorika.

The least-significant bit of the first octet is cleared to enforce unicast.

Local mode sets the next bit to indicate local administration.

Generated addresses are not vendor-issued identities or proof of uniqueness across all systems.
Do not impersonate a real device on a network.

Are these vendor-assigned OUIs?

No. They are synthetic random addresses.

Are multicast addresses generated?

No. The multicast/group bit is always cleared.

What randomness is used?

The browser Web Crypto random-number generator.
