Which company owns MAC address prefix 48:FC:B8?

MAC address prefix 48:FC:B8 is registered to Woodstream Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:FC:B8 has a network interface built by Woodstream Corporation.

What is the OUI 48:FC:B8?

48:FC:B8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Woodstream Corporation. It covers every address from 48:FC:B8:00:00:00 to 48:FC:B8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-FC-B8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:FC:B8:00:00:00 that is 48:FC:B8 — 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 Woodstream Corporation located?

Woodstream Corporation is listed at 69 N. Locust Street Lititz PA US 17543 in the IEEE OUI registry entry for 48:FC:B8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
