Which company owns MAC address prefix 04:5E:0A?

MAC address prefix 04:5E:0A is registered to SHENZHEN TRANSCHAN TECHNOLOGY LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:5E:0A has a network interface built by SHENZHEN TRANSCHAN TECHNOLOGY LIMITED.

What is the OUI 04:5E:0A?

04:5E:0A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SHENZHEN TRANSCHAN TECHNOLOGY LIMITED. It covers every address from 04:5E:0A:00:00:00 to 04:5E:0A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-5E-0A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:5E:0A:00:00:00 that is 04:5E:0A — 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 TRANSCHAN TECHNOLOGY LIMITED located?

SHENZHEN TRANSCHAN TECHNOLOGY LIMITED is listed at Room 03, 23/F, Unit B Building, No 9, Shenzhen Bay Eco -Technology Park, Yuehai Street, Nanshan District, Shenzhen, China Shenzhen CN 518000 in the IEEE OUI registry entry for 04:5E:0A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
