Which company owns MAC address prefix 00:0A:74?

MAC address prefix 00:0A:74 is registered to Manticom Networks Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0A:74 has a network interface built by Manticom Networks Inc..

What is the OUI 00:0A:74?

00:0A:74 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Manticom Networks Inc.. It covers every address from 00:0A:74:00:00:00 to 00:0A:74:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0A-74.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0A:74:00:00:00 that is 00:0A:74 — 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 Manticom Networks Inc. located?

Manticom Networks Inc. is listed at 14016-C Sullyfield Circle Chantilly VA US 20151 in the IEEE OUI registry entry for 00:0A:74. This is the address the organization registered with the IEEE, which may differ from its current operating address.
