Which company owns MAC address prefix 84:07:C4?

MAC address prefix 84:07:C4 is registered to Walter Kidde Portable Equipment, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:07:C4 has a network interface built by Walter Kidde Portable Equipment, Inc..

What is the OUI 84:07:C4?

84:07:C4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Walter Kidde Portable Equipment, Inc.. It covers every address from 84:07:C4:00:00:00 to 84:07:C4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-07-C4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:07:C4:00:00:00 that is 84:07:C4 — 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 Walter Kidde Portable Equipment, Inc. located?

Walter Kidde Portable Equipment, Inc. is listed at 1016 Corporate Park Rd Mebane NC US 27302 in the IEEE OUI registry entry for 84:07:C4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
