Which company owns MAC address prefix F0:AA:0B?

MAC address prefix F0:AA:0B is registered to Arra Networks/ Spectramesh in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:AA:0B has a network interface built by Arra Networks/ Spectramesh.

What is the OUI F0:AA:0B?

F0:AA:0B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Arra Networks/ Spectramesh. It covers every address from F0:AA:0B:00:00:00 to F0:AA:0B:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-AA-0B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:AA:0B:00:00:00 that is F0:AA:0B — 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 Arra Networks/ Spectramesh located?

Arra Networks/ Spectramesh is listed at 9201 Ward Pkwy #101 Kansas City MO US 64114 in the IEEE OUI registry entry for F0:AA:0B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
