Which company owns MAC address prefix 00:93:63?

MAC address prefix 00:93:63 is registered to Uni-Link Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:93:63 has a network interface built by Uni-Link Technology Co., Ltd..

What is the OUI 00:93:63?

00:93:63 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Uni-Link Technology Co., Ltd.. It covers every address from 00:93:63:00:00:00 to 00:93:63:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-93-63.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:93:63:00:00:00 that is 00:93:63 — 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 Uni-Link Technology Co., Ltd. located?

Uni-Link Technology Co., Ltd. is listed at 7-5, No.66, Sec.2, Nan-Kan Rd., Lu-Chu Hsiang,Taoyuan,Taiwan Taoyuan Taiwan TW 338 in the IEEE OUI registry entry for 00:93:63. This is the address the organization registered with the IEEE, which may differ from its current operating address.
