Which company owns MAC address prefix B8:AD:3E?

MAC address prefix B8:AD:3E is registered to BLUECOM in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:AD:3E has a network interface built by BLUECOM.

What is the OUI B8:AD:3E?

B8:AD:3E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BLUECOM. It covers every address from B8:AD:3E:00:00:00 to B8:AD:3E:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-AD-3E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:AD:3E:00:00:00 that is B8:AD:3E — 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 BLUECOM located?

BLUECOM is listed at 116, Venture-ro, Yeonsu-gu, Incheon KR 406-840 in the IEEE OUI registry entry for B8:AD:3E. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does BLUECOM own?

BLUECOM holds 2 OUI prefixes in the IEEE registry, of which B8:AD:3E is one. A device made by BLUECOM could carry a MAC address from any of them.
