Which company owns MAC address prefix 18:F4:6A?

MAC address prefix 18:F4:6A is registered to Hon Hai Precision Ind. Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:F4:6A has a network interface built by Hon Hai Precision Ind. Co.,Ltd..

What is the OUI 18:F4:6A?

18:F4:6A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hon Hai Precision Ind. Co.,Ltd.. It covers every address from 18:F4:6A:00:00:00 to 18:F4:6A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-F4-6A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:F4:6A:00:00:00 that is 18:F4:6A — 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 Hon Hai Precision Ind. Co.,Ltd. located?

Hon Hai Precision Ind. Co.,Ltd. is listed at Building D21,No.1, East Zone 1st Road Chongqing Chongqing CN 401332 in the IEEE OUI registry entry for 18:F4:6A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
