Which company owns MAC address prefix 84:68:C8?

MAC address prefix 84:68:C8 is registered to TOTOLINK TECHNOLOGY INT‘L LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:68:C8 has a network interface built by TOTOLINK TECHNOLOGY INT‘L LIMITED.

What is the OUI 84:68:C8?

84:68:C8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TOTOLINK TECHNOLOGY INT‘L LIMITED. It covers every address from 84:68:C8:00:00:00 to 84:68:C8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-68-C8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:68:C8:00:00:00 that is 84:68:C8 — 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 TOTOLINK TECHNOLOGY INT‘L LIMITED located?

TOTOLINK TECHNOLOGY INT‘L LIMITED is listed at ROOM 702,7/F SPA CENTER NO 53055 LOCKHART ROAD WAN CHAI HK 999077 in the IEEE OUI registry entry for 84:68:C8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
