Which company owns MAC address prefix 20:BB:C6?

MAC address prefix 20:BB:C6 is registered to Jabil Circuit Hungary Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:BB:C6 has a network interface built by Jabil Circuit Hungary Ltd..

What is the OUI 20:BB:C6?

20:BB:C6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Jabil Circuit Hungary Ltd.. It covers every address from 20:BB:C6:00:00:00 to 20:BB:C6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-BB-C6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:BB:C6:00:00:00 that is 20:BB:C6 — 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 Jabil Circuit Hungary Ltd. located?

Jabil Circuit Hungary Ltd. is listed at Huszár Andor 1. Tiszaújváros HU H-3580 in the IEEE OUI registry entry for 20:BB:C6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
