Which company owns MAC address prefix 48:D8:90?

MAC address prefix 48:D8:90 is registered to FN-LINK TECHNOLOGY LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:D8:90 has a network interface built by FN-LINK TECHNOLOGY LIMITED.

What is the OUI 48:D8:90?

48:D8:90 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FN-LINK TECHNOLOGY LIMITED. It covers every address from 48:D8:90:00:00:00 to 48:D8:90:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-D8-90.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:D8:90:00:00:00 that is 48:D8:90 — 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 FN-LINK TECHNOLOGY LIMITED located?

FN-LINK TECHNOLOGY LIMITED is listed at A Building,HuiXin industial park,No 31, YongHe road, Fuyong town, Bao'an District SHENZHEN GUANGDONG CN 518100 in the IEEE OUI registry entry for 48:D8:90. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does FN-LINK TECHNOLOGY LIMITED own?

FN-LINK TECHNOLOGY LIMITED holds 21 OUI prefixes in the IEEE registry, of which 48:D8:90 is one. A device made by FN-LINK TECHNOLOGY LIMITED could carry a MAC address from any of them.
