Which company owns MAC address prefix 60:C0:BF?

MAC address prefix 60:C0:BF is registered to ON Semiconductor in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:C0:BF has a network interface built by ON Semiconductor.

What is the OUI 60:C0:BF?

60:C0:BF is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ON Semiconductor. It covers every address from 60:C0:BF:00:00:00 to 60:C0:BF:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-C0-BF.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:C0:BF:00:00:00 that is 60:C0:BF — 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 ON Semiconductor located?

ON Semiconductor is listed at 5005 East McDowell Road Phoenix AZ US 85008 in the IEEE OUI registry entry for 60:C0:BF. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does ON Semiconductor own?

ON Semiconductor holds 2 OUI prefixes in the IEEE registry, of which 60:C0:BF is one. A device made by ON Semiconductor could carry a MAC address from any of them.

ON Semiconductor

MAC address prefix 60:C0:BF is registered to ON Semiconductor in the IEEE OUI registry. Any device whose MAC address begins with 60:C0:BF has a network interface built by ON Semiconductor. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 60:C0:BF:00:00:00 to 60:C0:BF:FF:FF:FF.
