Which company owns MAC address prefix 04:84:8A?

MAC address prefix 04:84:8A is registered to 7INOVA TECHNOLOGY LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:84:8A has a network interface built by 7INOVA TECHNOLOGY LIMITED.

What is the OUI 04:84:8A?

04:84:8A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to 7INOVA TECHNOLOGY LIMITED. It covers every address from 04:84:8A:00:00:00 to 04:84:8A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-84-8A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:84:8A:00:00:00 that is 04:84:8A — 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 7INOVA TECHNOLOGY LIMITED located?

7INOVA TECHNOLOGY LIMITED is listed at 3F, A Building, QuanYuanFa Industrial Park, No. 72, GuanLan Rd LongHua District Shenzhen CN 518000 in the IEEE OUI registry entry for 04:84:8A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
