Which company owns MAC address prefix E0:BE:03?

MAC address prefix E0:BE:03 is registered to Lite-On Network Communication (Dongguan) Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:BE:03 has a network interface built by Lite-On Network Communication (Dongguan) Limited.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:BE:03:00:00:00 that is E0:BE:03 — 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.
