Which company owns MAC address prefix 40:BC:60?

MAC address prefix 40:BC:60 is registered to Apple, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 40:BC:60 has a network interface built by Apple, Inc..

What is the OUI 40:BC:60?

40:BC:60 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Apple, Inc.. It covers every address from 40:BC:60:00:00:00 to 40:BC:60:FF:FF:FF, or 16,777,216 addresses in total. It is also written 40-BC-60.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 40:BC:60:00:00:00 that is 40:BC:60 — 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 Apple, Inc. located?

Apple, Inc. is listed at 1 Infinite Loop Cupertino CA US 95014 in the IEEE OUI registry entry for 40:BC:60. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Apple, Inc. own?

Apple, Inc. holds 1553 OUI prefixes in the IEEE registry, of which 40:BC:60 is one. A device made by Apple, Inc. could carry a MAC address from any of them.
