What is the OUI 14:78:0B?

14:78:0B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Varex Imaging Deutschland AG. It covers every address from 14:78:0B:00:00:00 to 14:78:0B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-78-0B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:78:0B:00:00:00 that is 14:78:0B — 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 Varex Imaging Deutschland AG located?

Varex Imaging Deutschland AG is listed at Zweigniederlassung/Branch Walluf In der Rehbach 22 Walluf DE 65396 in the IEEE OUI registry entry for 14:78:0B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
