Which company owns MAC address prefix A4:4C:62?

MAC address prefix A4:4C:62 is registered to Hangzhou Microimage Software Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A4:4C:62 has a network interface built by Hangzhou Microimage Software Co., Ltd.

What is the OUI A4:4C:62?

A4:4C:62 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hangzhou Microimage Software Co., Ltd. It covers every address from A4:4C:62:00:00:00 to A4:4C:62:FF:FF:FF, or 16,777,216 addresses in total. It is also written A4-4C-62.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A4:4C:62:00:00:00 that is A4:4C:62 — 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 Hangzhou Microimage Software Co., Ltd located?

Hangzhou Microimage Software Co., Ltd is listed at Room 313, Unit B, Building 2, 399 Danfeng Road, Binjiang District Hangzhou Zhejiang CN 310051 in the IEEE OUI registry entry for A4:4C:62.
