Which company owns MAC address prefix 14:43:19?

MAC address prefix 14:43:19 is registered to Creative&Link Technology Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:43:19 has a network interface built by Creative&Link Technology Limited.

What is the OUI 14:43:19?

14:43:19 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Creative&Link Technology Limited. It covers every address from 14:43:19:00:00:00 to 14:43:19:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-43-19.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:43:19:00:00:00 that is 14:43:19 — 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 Creative&Link Technology Limited located?

Creative&Link Technology Limited is listed at ROOM 704 HONG JIN GE BLD. NO.3018,YANHE SOUTH ROAD Shenzhen Guangdong US 518002 in the IEEE OUI registry entry for 14:43:19. This is the address the organization registered with the IEEE, which may differ from its current operating address.
