Which company owns MAC address prefix 1C:B0:44?

MAC address prefix 1C:B0:44 is registered to ASKEY COMPUTER CORP in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:B0:44 has a network interface built by ASKEY COMPUTER CORP.

What is the OUI 1C:B0:44?

1C:B0:44 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ASKEY COMPUTER CORP. It covers every address from 1C:B0:44:00:00:00 to 1C:B0:44:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-B0-44.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:B0:44:00:00:00 that is 1C:B0:44 — 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 ASKEY COMPUTER CORP located?
