Which company owns MAC address prefix F0:F6:44?

MAC address prefix F0:F6:44 is registered to Whitesky Science & Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:F6:44 has a network interface built by Whitesky Science & Technology Co.,Ltd..

What is the OUI F0:F6:44?

F0:F6:44 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Whitesky Science & Technology Co.,Ltd.. It covers every address from F0:F6:44:00:00:00 to F0:F6:44:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-F6-44.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:F6:44:00:00:00 that is F0:F6:44 — 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 Whitesky Science & Technology Co.,Ltd. located?

Whitesky Science & Technology Co.,Ltd. is listed at Room301,Building7,NO.6,Lane365 Shanghai CN 200052 in the IEEE OUI registry entry for F0:F6:44. This is the address the organization registered with the IEEE, which may differ from its current operating address.
