Which company owns MAC address prefix A8:6A:CB?

MAC address prefix A8:6A:CB is registered to EVAR in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:6A:CB has a network interface built by EVAR.

What is the OUI A8:6A:CB?

A8:6A:CB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EVAR. It covers every address from A8:6A:CB:00:00:00 to A8:6A:CB:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-6A-CB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:6A:CB:00:00:00 that is A8:6A:CB — 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 EVAR located?

EVAR is listed at 42, Changeop-ro, Sujeong-gu, Seongnam-si, Gyeonggi-do, Republic of Korea Seoul Gyunggi-do KR 13449 in the IEEE OUI registry entry for A8:6A:CB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
