Which company owns MAC address prefix F8:FF:0B?

MAC address prefix F8:FF:0B is registered to Electronic Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:FF:0B has a network interface built by Electronic Technology Inc..

What is the OUI F8:FF:0B?

F8:FF:0B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Electronic Technology Inc.. It covers every address from F8:FF:0B:00:00:00 to F8:FF:0B:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-FF-0B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:FF:0B:00:00:00 that is F8:FF: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 Electronic Technology Inc. located?

Electronic Technology Inc. is listed at 511 Lyons Ave Irvington NJ US 07111 in the IEEE OUI registry entry for F8:FF:0B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
