Which company owns MAC address prefix 00:12:0E?

MAC address prefix 00:12:0E is registered to AboCom in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:12:0E has a network interface built by AboCom.

What is the OUI 00:12:0E?

00:12:0E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AboCom. It covers every address from 00:12:0E:00:00:00 to 00:12:0E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-12-0E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:12:0E:00:00:00 that is 00:12:0E — 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 AboCom located?

AboCom is listed at 1F , No. 21, Yanfa 2nd Rd., SBIP Hsinchu City TW 300 in the IEEE OUI registry entry for 00:12:0E. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does AboCom own?

AboCom holds 3 OUI prefixes in the IEEE registry, of which 00:12:0E is one. A device made by AboCom could carry a MAC address from any of them.
