Which company owns MAC address prefix B4:BA:02?

MAC address prefix B4:BA:02 is registered to Agatel Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:BA:02 has a network interface built by Agatel Ltd.

What is the OUI B4:BA:02?

B4:BA:02 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Agatel Ltd. It covers every address from B4:BA:02:00:00:00 to B4:BA:02:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-BA-02.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:BA:02:00:00:00 that is B4:BA:02 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Agatel Ltd located?

Agatel Ltd is listed at Apex House, Calthrope Road Birmingham — GB B15 1TR in the IEEE OUI registry entry for B4:BA:02. This is the address the organization registered with the IEEE, which may differ from its current operating address.
