Which company owns MAC address prefix F4:BD:7C?

MAC address prefix F4:BD:7C is registered to Chengdu jinshi communication Co., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F4:BD:7C has a network interface built by Chengdu jinshi communication Co., LTD.

What is the OUI F4:BD:7C?

F4:BD:7C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Chengdu jinshi communication Co., LTD. It covers every address from F4:BD:7C:00:00:00 to F4:BD:7C:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-BD-7C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:BD:7C:00:00:00 that is F4:BD:7C — 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 Chengdu jinshi communication Co., LTD located?

Chengdu jinshi communication Co., LTD is listed at No. 108 #1-2-505, Eastern 5 Section, First Ring Road, JinJiang District, Chengdu Chongqing CN 610000 in the IEEE OUI registry entry for F4:BD:7C.
