Which company owns MAC address prefix 04:6E:49?

MAC address prefix 04:6E:49 is registered to TaiYear Electronic Technology (Suzhou) Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:6E:49 has a network interface built by TaiYear Electronic Technology (Suzhou) Co., Ltd.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:6E:49:00:00:00 that is 04:6E:49 — 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.
