Which company owns MAC address prefix C0:47:0E?

MAC address prefix C0:47:0E is registered to Dell Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:47:0E has a network interface built by Dell Inc..

What is the OUI C0:47:0E?

C0:47:0E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Dell Inc.. It covers every address from C0:47:0E:00:00:00 to C0:47:0E:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-47-0E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:47:0E:00:00:00 that is C0:47:0E — 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 Dell Inc. located?

Dell Inc. is listed at One Dell Way Round Rock TX US 78682 in the IEEE OUI registry entry for C0:47:0E. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Dell Inc. own?

Dell Inc. holds 184 OUI prefixes in the IEEE registry, of which C0:47:0E is one. A device made by Dell Inc. could carry a MAC address from any of them.
