Which company owns MAC address prefix 60:61:DF?

MAC address prefix 60:61:DF is registered to Z-meta Research LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:61:DF has a network interface built by Z-meta Research LLC.

What is the OUI 60:61:DF?

60:61:DF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Z-meta Research LLC. It covers every address from 60:61:DF:00:00:00 to 60:61:DF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-61-DF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:61:DF:00:00:00 that is 60:61:DF — 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 Z-meta Research LLC located?

Z-meta Research LLC is listed at 8365 Quay Drive Arvada CO US 80003 in the IEEE OUI registry entry for 60:61:DF. This is the address the organization registered with the IEEE, which may differ from its current operating address.
