Which company owns MAC address prefix F4:67:2D?

MAC address prefix F4:67:2D is registered to ShenZhen Topstar Technology Company in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F4:67:2D has a network interface built by ShenZhen Topstar Technology Company.

What is the OUI F4:67:2D?

F4:67:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ShenZhen Topstar Technology Company. It covers every address from F4:67:2D:00:00:00 to F4:67:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-67-2D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:67:2D:00:00:00 that is F4:67:2D — 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 Topstar Technology Company located?

ShenZhen Topstar Technology Company is listed at 5/F Buliding 204,Tai Ran ShenZhen Science&Industry Park ShenZhen GuangZhou CN 518042 in the IEEE OUI registry entry for F4:67:2D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
