Which company owns MAC address prefix F8:C0:01?

MAC address prefix F8:C0:01 is registered to Juniper Networks in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:C0:01 has a network interface built by Juniper Networks.

What is the OUI F8:C0:01?

F8:C0:01 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Juniper Networks. It covers every address from F8:C0:01:00:00:00 to F8:C0:01:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-C0-01.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:C0:01:00:00:00 that is F8:C0:01 — 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 Juniper Networks located?

Juniper Networks is listed at 1133 Innovation Way Sunnyvale CA US 94089 in the IEEE OUI registry entry for F8:C0:01. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Juniper Networks own?

Juniper Networks holds 211 OUI prefixes in the IEEE registry, of which F8:C0:01 is one. A device made by Juniper Networks could carry a MAC address from any of them.
