What is the OUI 20:55:32?

20:55:32 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Gotech International Technology Limited. It covers every address from 20:55:32:00:00:00 to 20:55:32:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-55-32.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:55:32:00:00:00 that is 20:55:32 — 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 Gotech International Technology Limited located?

Gotech International Technology Limited is listed at Unit 2506, 25/F, Prosperity Place,6 Shing Yip Street, Kwun Tong, Kowloon Hong Kong CN 00000 in the IEEE OUI registry entry for 20:55:32.
