Which company owns MAC address prefix 44:D9:80?

MAC address prefix 44:D9:80 is registered to EVERYBOT INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:D9:80 has a network interface built by EVERYBOT INC..

What is the OUI 44:D9:80?

44:D9:80 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EVERYBOT INC.. It covers every address from 44:D9:80:00:00:00 to 44:D9:80:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-D9-80.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:D9:80:00:00:00 that is 44:D9:80 — 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 EVERYBOT INC. located?

EVERYBOT INC. is listed at 10th Floor of H Square B/D S, Pangyoyeok-ro 231, Bundang-gu Seongnam-si Gyeonggi-do KR 13494 in the IEEE OUI registry entry for 44:D9:80. This is the address the organization registered with the IEEE, which may differ from its current operating address.
