Which company owns MAC address prefix B0:E7:DE?

MAC address prefix B0:E7:DE is registered to Homa Technologies JSC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B0:E7:DE has a network interface built by Homa Technologies JSC.

What is the OUI B0:E7:DE?

B0:E7:DE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Homa Technologies JSC. It covers every address from B0:E7:DE:00:00:00 to B0:E7:DE:FF:FF:FF, or 16,777,216 addresses in total. It is also written B0-E7-DE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B0:E7:DE:00:00:00 that is B0:E7:DE — 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 Homa Technologies JSC located?

Homa Technologies JSC is listed at Building 5, Quang Trung Software City, District 12 Ho Chi Minh VN 729226 in the IEEE OUI registry entry for B0:E7:DE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
