Which company owns MAC address prefix 00:0B:2E?

MAC address prefix 00:0B:2E is registered to Cal-Comp Electronics & Communications Company Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0B:2E has a network interface built by Cal-Comp Electronics & Communications Company Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0B:2E:00:00:00 that is 00:0B:2E — 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.

How many MAC prefixes does Cal-Comp Electronics & Communications Company Ltd. own?

Cal-Comp Electronics & Communications Company Ltd. holds 3 OUI prefixes in the IEEE registry, of which 00:0B:2E is one. A device made by Cal-Comp Electronics & Communications Company Ltd. could carry a MAC address from any of them.
