What is the OUI 9C:F8:DB?

9C:F8:DB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to shenzhen eyunmei technology co,.ltd. It covers every address from 9C:F8:DB:00:00:00 to 9C:F8:DB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-F8-DB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:F8:DB:00:00:00 that is 9C:F8:DB — 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 shenzhen eyunmei technology co,.ltd located?
