Which company owns MAC address prefix 80:DE:CC?

MAC address prefix 80:DE:CC is registered to HYBE Co.,LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:DE:CC has a network interface built by HYBE Co.,LTD.

What is the OUI 80:DE:CC?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:DE:CC:00:00:00 that is 80:DE:CC — 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 HYBE Co.,LTD located?

HYBE Co.,LTD is listed at 42, Hangang-daero Yongsan-gu Seoul KR 04389 in the IEEE OUI registry entry for 80:DE:CC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
