Which company owns MAC address prefix 9C:93:4E?

MAC address prefix 9C:93:4E is registered to Xerox Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:93:4E has a network interface built by Xerox Corporation.

What is the OUI 9C:93:4E?

9C:93:4E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Xerox Corporation. It covers every address from 9C:93:4E:00:00:00 to 9C:93:4E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-93-4E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:93:4E:00:00:00 that is 9C:93:4E — 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 Xerox Corporation located?

Xerox Corporation is listed at Mail Stop 0214 - 7E Webster NY US 14580 in the IEEE OUI registry entry for 9C:93:4E. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Xerox Corporation own?

Xerox Corporation holds 2 OUI prefixes in the IEEE registry, of which 9C:93:4E is one. A device made by Xerox Corporation could carry a MAC address from any of them.
