FAQ
- Which company owns MAC address prefix F8:A2:B4?
- MAC address prefix F8:A2:B4 is registered to RHEWA-WAAGENFABRIK August Freudewald GmbH &Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:A2:B4 has a network interface built by RHEWA-WAAGENFABRIK August Freudewald GmbH &Co. KG.
- What is the OUI F8:A2:B4?
- F8:A2:B4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to RHEWA-WAAGENFABRIK August Freudewald GmbH &Co. KG. It covers every address from F8:A2:B4:00:00:00 to F8:A2:B4:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-A2-B4.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in F8:A2:B4:00:00:00 that is F8:A2:B4 — 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.
