Which company owns MAC address prefix B0:61:C7?

MAC address prefix B0:61:C7 is registered to Ericsson-LG Enterprise in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:61:C7 has a network interface built by Ericsson-LG Enterprise.

What is the OUI B0:61:C7?

B0:61:C7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ericsson-LG Enterprise. It covers every address from B0:61:C7:00:00:00 to B0:61:C7:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-61-C7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:61:C7:00:00:00 that is B0:61:C7 — 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 Ericsson-LG Enterprise located?

Ericsson-LG Enterprise is listed at 77, Heungan-daro 81beon-gil, Anyang Gyeonggi KR 431-749 in the IEEE OUI registry entry for B0:61:C7. This is the address the organization registered with the IEEE, which may differ from its current operating address.
