Which company owns MAC address prefix 1C:AB:C0?

MAC address prefix 1C:AB:C0 is registered to Hitron Technologies. Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:AB:C0 has a network interface built by Hitron Technologies. Inc.

What is the OUI 1C:AB:C0?

1C:AB:C0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hitron Technologies. Inc. It covers every address from 1C:AB:C0:00:00:00 to 1C:AB:C0:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-AB-C0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:AB:C0:00:00:00 that is 1C:AB:C0 — 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 Hitron Technologies. Inc located?

Hitron Technologies. Inc is listed at No. 1-8, Lising 1st Rd. Hsinchu Science Park, Hsinchu, 300, Taiwan, R.O.C Hsin-chu Taiwan TW 300 in the IEEE OUI registry entry for 1C:AB:C0. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Hitron Technologies. Inc own?

Hitron Technologies. Inc holds 32 OUI prefixes in the IEEE registry, of which 1C:AB:C0 is one. A device made by Hitron Technologies. Inc could carry a MAC address from any of them.
