Which company owns MAC address prefix 78:BE:B6?

MAC address prefix 78:BE:B6 is registered to Enhanced Vision in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 78:BE:B6 has a network interface built by Enhanced Vision.

What is the OUI 78:BE:B6?

78:BE:B6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Enhanced Vision. It covers every address from 78:BE:B6:00:00:00 to 78:BE:B6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 78-BE-B6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 78:BE:B6:00:00:00 that is 78:BE:B6 — 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 Enhanced Vision located?

Enhanced Vision is listed at 5882 MACHINE DR. Huntington Beach California US 92649 in the IEEE OUI registry entry for 78:BE:B6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
