What is the OUI 48:C8:62?

48:C8:62 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Simo Wireless,Inc.. It covers every address from 48:C8:62:00:00:00 to 48:C8:62:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-C8-62.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:C8:62:00:00:00 that is 48:C8:62 — 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 Simo Wireless,Inc. located?
