Which company owns MAC address prefix D0:AF:B6?

MAC address prefix D0:AF:B6 is registered to Linktop Technology Co., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:AF:B6 has a network interface built by Linktop Technology Co., LTD.

What is the OUI D0:AF:B6?

D0:AF:B6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Linktop Technology Co., LTD. It covers every address from D0:AF:B6:00:00:00 to D0:AF:B6:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-AF-B6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:AF:B6:00:00:00 that is D0:AF:B6 — 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 Linktop Technology Co., LTD located?

Linktop Technology Co., LTD is listed at 2F Guangye Buliding, Torch Hi-Tech, Xiamen Fujian CN 361006 in the IEEE OUI registry entry for D0:AF:B6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
