Which company owns MAC address prefix 14:EA:A1?

MAC address prefix 14:EA:A1 is registered to Micronet union Technology (chengdu) co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:EA:A1 has a network interface built by Micronet union Technology (chengdu) co., Ltd.

What is the OUI 14:EA:A1?

14:EA:A1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Micronet union Technology (chengdu) co., Ltd. It covers every address from 14:EA:A1:00:00:00 to 14:EA:A1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-EA-A1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:EA:A1:00:00:00 that is 14:EA:A1 — 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 Micronet union Technology (chengdu) co., Ltd located?
