Which company owns MAC address prefix 24:53:BF?

MAC address prefix 24:53:BF is registered to Enernet in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:53:BF has a network interface built by Enernet.

What is the OUI 24:53:BF?

24:53:BF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Enernet. It covers every address from 24:53:BF:00:00:00 to 24:53:BF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-53-BF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:53:BF:00:00:00 that is 24:53:BF — 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 Enernet located?

Enernet is listed at 1007 B-dong, Hyundai Knowledge Industry Center, 70 Dusan-ro, Geumcheon-gu, Seoul, KOREA SEOUL KR 08584 in the IEEE OUI registry entry for 24:53:BF. This is the address the organization registered with the IEEE, which may differ from its current operating address.
