Which company owns MAC address prefix 2C:DD:A3?

MAC address prefix 2C:DD:A3 is registered to Point Grey Research Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:DD:A3 has a network interface built by Point Grey Research Inc..

What is the OUI 2C:DD:A3?

2C:DD:A3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Point Grey Research Inc.. It covers every address from 2C:DD:A3:00:00:00 to 2C:DD:A3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-DD-A3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:DD:A3:00:00:00 that is 2C:DD:A3 — 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 Point Grey Research Inc. located?

Point Grey Research Inc. is listed at 305-1847 West Broadway Vancouver British Columbia V6J 1Y6 CA in the IEEE OUI registry entry for 2C:DD:A3. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Point Grey Research Inc. own?

Point Grey Research Inc. holds 2 OUI prefixes in the IEEE registry, of which 2C:DD:A3 is one. A device made by Point Grey Research Inc. could carry a MAC address from any of them.
