Which company owns MAC address prefix 00:09:BC?

MAC address prefix 00:09:BC is registered to Utility, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:09:BC has a network interface built by Utility, Inc.

What is the OUI 00:09:BC?

00:09:BC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Utility, Inc. It covers every address from 00:09:BC:00:00:00 to 00:09:BC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-09-BC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:09:BC:00:00:00 that is 00:09:BC — 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 Utility, Inc located?

Utility, Inc is listed at 250 E Ponce de Leon Ave Suite 700 Decatur GA US 30030 in the IEEE OUI registry entry for 00:09:BC. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Utility, Inc own?

Utility, Inc holds 2 OUI prefixes in the IEEE registry, of which 00:09:BC is one. A device made by Utility, Inc could carry a MAC address from any of them.
