Which company owns MAC address prefix 64:26:77?

MAC address prefix 64:26:77 is registered to BKM-Micronic Richtfunkanlagen GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:26:77 has a network interface built by BKM-Micronic Richtfunkanlagen GmbH.

What is the OUI 64:26:77?

64:26:77 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BKM-Micronic Richtfunkanlagen GmbH. It covers every address from 64:26:77:00:00:00 to 64:26:77:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-26-77.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:26:77:00:00:00 that is 64:26:77 — 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 BKM-Micronic Richtfunkanlagen GmbH located?

BKM-Micronic Richtfunkanlagen GmbH is listed at Im Steinernen Kreuz 19 Wurmberg DE 75449 in the IEEE OUI registry entry for 64:26:77. This is the address the organization registered with the IEEE, which may differ from its current operating address.
