Which company owns MAC address prefix E0:4B:41?

MAC address prefix E0:4B:41 is registered to Hangzhou Beilian Low Carbon Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:4B:41 has a network interface built by Hangzhou Beilian Low Carbon Technology Co., Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:4B:41:00:00:00 that is E0:4B:41 — 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 Beilian Low Carbon Technology Co., Ltd. located?

Hangzhou Beilian Low Carbon Technology Co., Ltd. is listed at Room 2502, area a, building 1, No. 57, jianger Road, Changhe street, Binjiang District, HangZhou ZheJiang CN 310000 in the IEEE OUI registry entry for E0:4B:41. This is the address the organization registered with the IEEE, which may differ from its current operating address.
