Which company owns MAC address prefix 3C:CA:87?

What is the OUI 3C:CA:87?

3C:CA:87 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Iders Incorporated. It covers every address from 3C:CA:87:00:00:00 to 3C:CA:87:FF:FF:FF, or 16,777,216 addresses in total. It is also written 3C-CA-87.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 3C:CA:87:00:00:00 that is 3C:CA:87 — 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 Iders Incorporated located?

Iders Incorporated is listed at 27047 Oakwood Rd Oakbank Manitoba CA R0E 1J2 in the IEEE OUI registry entry for 3C:CA:87. This is the address the organization registered with the IEEE, which may differ from its current operating address.
