What is the OUI 14:48:02?

14:48:02 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to THE YEOLRIM Co.,Ltd.. It covers every address from 14:48:02:00:00:00 to 14:48:02:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-48-02.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:48:02:00:00:00 that is 14:48:02 — 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.
