Which company owns MAC address prefix 00:04:9E?

MAC address prefix 00:04:9E is registered to Wirelink Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:04:9E has a network interface built by Wirelink Co., Ltd..

What is the OUI 00:04:9E?

00:04:9E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wirelink Co., Ltd.. It covers every address from 00:04:9E:00:00:00 to 00:04:9E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-04-9E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:04:9E:00:00:00 that is 00:04:9E — 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 Wirelink Co., Ltd. located?

Wirelink Co., Ltd. is listed at 11F, Geoseong B/D 541, Dowha-Dong, KR KOREA in the IEEE OUI registry entry for 00:04:9E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
