Which company owns MAC address prefix 2C:E3:10?

MAC address prefix 2C:E3:10 is registered to Stratacache in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:E3:10 has a network interface built by Stratacache.

What is the OUI 2C:E3:10?

2C:E3:10 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Stratacache. It covers every address from 2C:E3:10:00:00:00 to 2C:E3:10:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-E3-10.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:E3:10:00:00:00 that is 2C:E3:10 — 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 Stratacache located?

Stratacache is listed at 40 N Main St, Suite 2600 Dayton OH US 45423 in the IEEE OUI registry entry for 2C:E3:10. This is the address the organization registered with the IEEE, which may differ from its current operating address.
