Which company owns MAC address prefix 88:3C:93?

MAC address prefix 88:3C:93 is registered to Alcatel-Lucent Enterprise in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:3C:93 has a network interface built by Alcatel-Lucent Enterprise.

What is the OUI 88:3C:93?

88:3C:93 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Alcatel-Lucent Enterprise. It covers every address from 88:3C:93:00:00:00 to 88:3C:93:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-3C-93.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:3C:93:00:00:00 that is 88:3C:93 — 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 Enterprise located?

Alcatel-Lucent Enterprise is listed at 26801 West Agoura Rd Calabasas CA US 91301 in the IEEE OUI registry entry for 88:3C:93. 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 Enterprise own?

Alcatel-Lucent Enterprise holds 12 OUI prefixes in the IEEE registry, of which 88:3C:93 is one. A device made by Alcatel-Lucent Enterprise could carry a MAC address from any of them.
