Which company owns MAC address prefix 94:D4:17?

MAC address prefix 94:D4:17 is registered to GPI KOREA INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:D4:17 has a network interface built by GPI KOREA INC..

What is the OUI 94:D4:17?

94:D4:17 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GPI KOREA INC.. It covers every address from 94:D4:17:00:00:00 to 94:D4:17:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-D4-17.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:D4:17:00:00:00 that is 94:D4:17 — 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 GPI KOREA INC. located?

GPI KOREA INC. is listed at Daebang Triplaon B-Dong 201 Goyang-Si Kyeonggi-Do KR 410-704 in the IEEE OUI registry entry for 94:D4:17. This is the address the organization registered with the IEEE, which may differ from its current operating address.
