What is the OUI 30:29:BE?

30:29:BE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai MRDcom Co.,Ltd. It covers every address from 30:29:BE:00:00:00 to 30:29:BE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-29-BE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:29:BE:00:00:00 that is 30:29:BE — 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.
