Which company owns MAC address prefix 08:BA:B7?

MAC address prefix 08:BA:B7 is registered to Ceragon Networks Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:BA:B7 has a network interface built by Ceragon Networks Ltd..

What is the OUI 08:BA:B7?

08:BA:B7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ceragon Networks Ltd.. It covers every address from 08:BA:B7:00:00:00 to 08:BA:B7:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-BA-B7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:BA:B7:00:00:00 that is 08:BA:B7 — 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.
