Which company owns MAC address prefix D8:C2:62?

MAC address prefix D8:C2:62 is registered to Ubiquiti Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:C2:62 has a network interface built by Ubiquiti Inc.

What is the OUI D8:C2:62?

D8:C2:62 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ubiquiti Inc. It covers every address from D8:C2:62:00:00:00 to D8:C2:62:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-C2-62.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:C2:62:00:00:00 that is D8:C2:62 — 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 Ubiquiti Inc located?

Ubiquiti Inc is listed at 685 Third Avenue, 27th Floor New York NY US New York NY 10017 in the IEEE OUI registry entry for D8:C2:62. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Ubiquiti Inc own?

Ubiquiti Inc holds 48 OUI prefixes in the IEEE registry, of which D8:C2:62 is one. A device made by Ubiquiti Inc could carry a MAC address from any of them.
