MAC address prefix A4:D7:95 is registered to Wingtech Mobile Communications Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A4:D7:95 has a network interface built by Wingtech Mobile Communications Co.,Ltd.

What is the OUI A4:D7:95?

A4:D7:95 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wingtech Mobile Communications Co.,Ltd. It covers every address from A4:D7:95:00:00:00 to A4:D7:95:FF:FF:FF, or 16,777,216 addresses in total. It is also written A4-D7-95.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A4:D7:95:00:00:00 that is A4:D7:95 — 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 Wingtech Mobile Communications Co.,Ltd located?
