Which company owns MAC address prefix 80:19:FE?

MAC address prefix 80:19:FE is registered to JianLing Technology CO., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:19:FE has a network interface built by JianLing Technology CO., LTD.

What is the OUI 80:19:FE?

80:19:FE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JianLing Technology CO., LTD. It covers every address from 80:19:FE:00:00:00 to 80:19:FE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-19-FE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:19:FE:00:00:00 that is 80:19:FE — 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 JianLing Technology CO., LTD located?

JianLing Technology CO., LTD is listed at No. 383-1, Sec. 2, Jinling Rd., Pingzhen Dist., Tao Yuan TW 324 in the IEEE OUI registry entry for 80:19:FE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
