What is the OUI 44:36:5D?

44:36:5D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen HippStor Technology Co., Ltd. It covers every address from 44:36:5D:00:00:00 to 44:36:5D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-36-5D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:36:5D:00:00:00 that is 44:36:5D — 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 Shenzhen HippStor Technology Co., Ltd located?
