Which company owns MAC address prefix 68:DB:54?

MAC address prefix 68:DB:54 is registered to Phicomm (Shanghai) Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:DB:54 has a network interface built by Phicomm (Shanghai) Co., Ltd..

What is the OUI 68:DB:54?

68:DB:54 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Phicomm (Shanghai) Co., Ltd.. It covers every address from 68:DB:54:00:00:00 to 68:DB:54:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-DB-54.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:DB:54:00:00:00 that is 68:DB:54 — 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 Phicomm (Shanghai) Co., Ltd. located?
