Which company owns MAC address prefix D0:92:88?

MAC address prefix D0:92:88 is registered to Powertek Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:92:88 has a network interface built by Powertek Limited.

What is the OUI D0:92:88?

D0:92:88 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Powertek Limited. It covers every address from D0:92:88:00:00:00 to D0:92:88:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-92-88.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D0:92:88:00:00:00 that is D0:92:88 — 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 Powertek Limited located?

Powertek Limited is listed at C/Mirador d'Encamp 16 Torre 4 Baix 2n Encamp Encamp AD AD200 in the IEEE OUI registry entry for D0:92:88. This is the address the organization registered with the IEEE, which may differ from its current operating address.
