Which company owns MAC address prefix 94:AE:F0?

MAC address prefix 94:AE:F0 is registered to Cisco Systems, Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:AE:F0 has a network interface built by Cisco Systems, Inc.

What is the OUI 94:AE:F0?

94:AE:F0 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 94:AE:F0:00:00:00 to 94:AE:F0:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-AE-F0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:AE:F0:00:00:00 that is 94:AE:F0 — 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?

Cisco Systems, Inc is listed at 80 West Tasman Drive San Jose CA US 94568 in the IEEE OUI registry entry for 94:AE:F0. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Cisco Systems, Inc own?

Cisco Systems, Inc holds 1251 OUI prefixes in the IEEE registry, of which 94:AE:F0 is one. A device made by Cisco Systems, Inc could carry a MAC address from any of them.
