Which company owns MAC address prefix 04:7E:4A?

MAC address prefix 04:7E:4A is registered to moobox CO., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:7E:4A has a network interface built by moobox CO., Ltd..

What is the OUI 04:7E:4A?

04:7E:4A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to moobox CO., Ltd.. It covers every address from 04:7E:4A:00:00:00 to 04:7E:4A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-7E-4A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:7E:4A:00:00:00 that is 04:7E:4A — 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 moobox CO., Ltd. located?

moobox CO., Ltd. is listed at No 801, Yanchang Zhong Road Shanghai Shanghai CN 200072 in the IEEE OUI registry entry for 04:7E:4A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
