What is the OUI 54:54:14?

54:54:14 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Digital RF Corea, Inc. It covers every address from 54:54:14:00:00:00 to 54:54:14:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-54-14.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:54:14:00:00:00 that is 54:54:14 — 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 Digital RF Corea, Inc located?

Digital RF Corea, Inc is listed at 2 Floor, SeMin B/D, 201, Jangdari-ro Suwon-si Gyeonggi-do KR 442-833 in the IEEE OUI registry entry for 54:54:14. This is the address the organization registered with the IEEE, which may differ from its current operating address.
