Which company owns MAC address prefix F8:AC:6D?

MAC address prefix F8:AC:6D is registered to Deltenna Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:AC:6D has a network interface built by Deltenna Ltd.

What is the OUI F8:AC:6D?

F8:AC:6D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Deltenna Ltd. It covers every address from F8:AC:6D:00:00:00 to F8:AC:6D:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-AC-6D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:AC:6D:00:00:00 that is F8:AC:6D — 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 Deltenna Ltd located?

Deltenna Ltd is listed at First Floor Unit 2 Chippenham Wiltshire GB SN15 1BN in the IEEE OUI registry entry for F8:AC:6D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
