Which company owns MAC address prefix 0C:A4:02?

MAC address prefix 0C:A4:02 is registered to Alcatel-Lucent IPD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:A4:02 has a network interface built by Alcatel-Lucent IPD.

What is the OUI 0C:A4:02?

0C:A4:02 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Alcatel-Lucent IPD. It covers every address from 0C:A4:02:00:00:00 to 0C:A4:02:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-A4-02.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:A4:02:00:00:00 that is 0C:A4:02 — 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 Alcatel-Lucent IPD located?

Alcatel-Lucent IPD is listed at 600 March Drive Kanata Ontario CA K2K2E6 in the IEEE OUI registry entry for 0C:A4:02. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Alcatel-Lucent IPD own?

Alcatel-Lucent IPD holds 11 OUI prefixes in the IEEE registry, of which 0C:A4:02 is one. A device made by Alcatel-Lucent IPD could carry a MAC address from any of them.
