How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:27:CE:00:00:00 that is 84:27:CE — 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.
