Which company owns MAC address prefix 90:1D:FF?

MAC address prefix 90:1D:FF is registered to ZOWEE TECHNOLOGY(HEYUAN)Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:1D:FF has a network interface built by ZOWEE TECHNOLOGY(HEYUAN)Co.,Ltd.

What is the OUI 90:1D:FF?

90:1D:FF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ZOWEE TECHNOLOGY(HEYUAN)Co.,Ltd. It covers every address from 90:1D:FF:00:00:00 to 90:1D:FF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-1D-FF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:1D:FF:00:00:00 that is 90:1D:FF — 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 ZOWEE TECHNOLOGY(HEYUAN)Co.,Ltd located?
