Which company owns MAC address prefix 60:3E:7B?

MAC address prefix 60:3E:7B is registered to Gafachi, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:3E:7B has a network interface built by Gafachi, Inc..

What is the OUI 60:3E:7B?

60:3E:7B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Gafachi, Inc.. It covers every address from 60:3E:7B:00:00:00 to 60:3E:7B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-3E-7B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:3E:7B:00:00:00 that is 60:3E:7B — 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 Gafachi, Inc. located?

Gafachi, Inc. is listed at 1 W Main St., STE 650 Rochester NY US 14614 in the IEEE OUI registry entry for 60:3E:7B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
