Which company owns MAC address prefix FC:CA:C4?

MAC address prefix FC:CA:C4 is registered to LifeHealth, LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:CA:C4 has a network interface built by LifeHealth, LLC.

What is the OUI FC:CA:C4?

FC:CA:C4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LifeHealth, LLC. It covers every address from FC:CA:C4:00:00:00 to FC:CA:C4:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-CA-C4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:CA:C4:00:00:00 that is FC:CA: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 LifeHealth, LLC located?

LifeHealth, LLC is listed at 2656 Patton Rd Roseville MN US 55113 in the IEEE OUI registry entry for FC:CA:C4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
