FAQ
- Which company owns MAC address prefix F8:C2:88?
- MAC address prefix F8:C2:88 is registered to Cisco Systems, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:C2:88 has a network interface built by Cisco Systems, Inc.
- What is the OUI F8:C2:88?
- F8:C2:88 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Cisco Systems, Inc. It covers every address from F8:C2:88:00:00:00 to F8:C2:88:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-C2-88.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in F8:C2:88:00:00:00 that is F8:C2:88 — 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 Cisco Systems, Inc located?
