Which company owns MAC address prefix D8:16:C1?

MAC address prefix D8:16:C1 is registered to DEWAV (HK) ELECTRONICS LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:16:C1 has a network interface built by DEWAV (HK) ELECTRONICS LIMITED.

What is the OUI D8:16:C1?

D8:16:C1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DEWAV (HK) ELECTRONICS LIMITED. It covers every address from D8:16:C1:00:00:00 to D8:16:C1:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-16-C1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:16:C1:00:00:00 that is D8:16:C1 — 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 DEWAV (HK) ELECTRONICS LIMITED located?

DEWAV (HK) ELECTRONICS LIMITED is listed at UNIT NO.1-2, 06/F., PERFECT INDUSTRIAL BUILDING,NO. 31 TAI YAU STREET, SAN PO KONG KOWLOON, HONG KONG CN 510610 in the IEEE OUI registry entry for D8:16:C1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
