Which company owns MAC address prefix 40:2E:28?

MAC address prefix 40:2E:28 is registered to MiXTelematics in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 40:2E:28 has a network interface built by MiXTelematics.

What is the OUI 40:2E:28?

40:2E:28 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MiXTelematics. It covers every address from 40:2E:28:00:00:00 to 40:2E:28:FF:FF:FF, or 16,777,216 addresses in total. It is also written 40-2E-28.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 40:2E:28:00:00:00 that is 40:2E:28 — 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 MiXTelematics located?

MiXTelematics is listed at Blaauwklip Office Park 2 Stellenbosch Cape Province ZA 7600 in the IEEE OUI registry entry for 40:2E:28. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does MiXTelematics own?

MiXTelematics holds 2 OUI prefixes in the IEEE registry, of which 40:2E:28 is one. A device made by MiXTelematics could carry a MAC address from any of them.
