Which company owns MAC address prefix 8C:E2:DA?

MAC address prefix 8C:E2:DA is registered to Circle Media Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 8C:E2:DA has a network interface built by Circle Media Inc.

What is the OUI 8C:E2:DA?

8C:E2:DA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Circle Media Inc. It covers every address from 8C:E2:DA:00:00:00 to 8C:E2:DA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 8C-E2-DA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 8C:E2:DA:00:00:00 that is 8C:E2:DA — 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 Circle Media Inc located?

Circle Media Inc is listed at 1319 SE Martin Luther King Jr. Blvd. Portland Oregon US 97214 in the IEEE OUI registry entry for 8C:E2:DA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
