Which company owns MAC address prefix 68:F1:25?

MAC address prefix 68:F1:25 is registered to Data Controls Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:F1:25 has a network interface built by Data Controls Inc..

What is the OUI 68:F1:25?

68:F1:25 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Data Controls Inc.. It covers every address from 68:F1:25:00:00:00 to 68:F1:25:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-F1-25.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:F1:25:00:00:00 that is 68:F1:25 — 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 Data Controls Inc. located?

Data Controls Inc. is listed at VORT Asakusabashi Ekimae Bldg V, Taito-ku Tokyo JP 111-0052 in the IEEE OUI registry entry for 68:F1:25. This is the address the organization registered with the IEEE, which may differ from its current operating address.
