What is the OUI 7C:E1:52?

7C:E1:52 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to THE GOODYEAR TIRE & RUBBER COMPANY. It covers every address from 7C:E1:52:00:00:00 to 7C:E1:52:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-E1-52.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:E1:52:00:00:00 that is 7C:E1:52 — 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 THE GOODYEAR TIRE & RUBBER COMPANY located?

THE GOODYEAR TIRE & RUBBER COMPANY is listed at 200 Innovation Way Akron OH US 44316 in the IEEE OUI registry entry for 7C:E1:52. This is the address the organization registered with the IEEE, which may differ from its current operating address.
