Which company owns MAC address prefix 00:60:6B?

MAC address prefix 00:60:6B is registered to Synclayer Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:60:6B has a network interface built by Synclayer Inc..

What is the OUI 00:60:6B?

00:60:6B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Synclayer Inc.. It covers every address from 00:60:6B:00:00:00 to 00:60:6B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-60-6B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:60:6B:00:00:00 that is 00:60:6B — 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 Synclayer Inc. located?

Synclayer Inc. is listed at 1-20 Himegaoka GIFU 509-0249 JP in the IEEE OUI registry entry for 00:60:6B. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Synclayer Inc. own?

Synclayer Inc. holds 2 OUI prefixes in the IEEE registry, of which 00:60:6B is one. A device made by Synclayer Inc. could carry a MAC address from any of them.
