Which company owns MAC address prefix 08:C6:B3?

MAC address prefix 08:C6:B3 is registered to QTECH LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:C6:B3 has a network interface built by QTECH LLC.

What is the OUI 08:C6:B3?

08:C6:B3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to QTECH LLC. It covers every address from 08:C6:B3:00:00:00 to 08:C6:B3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-C6-B3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:C6:B3:00:00:00 that is 08:C6:B3 — 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 QTECH LLC located?

QTECH LLC is listed at Novozavodskaya st. 18 build. 1 Moscow Moscow region RU 121309 in the IEEE OUI registry entry for 08:C6:B3. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does QTECH LLC own?

QTECH LLC holds 2 OUI prefixes in the IEEE registry, of which 08:C6:B3 is one. A device made by QTECH LLC could carry a MAC address from any of them.
