Which company owns MAC address prefix 9C:9E:03?

MAC address prefix 9C:9E:03 is registered to awayfrom in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:9E:03 has a network interface built by awayfrom.

What is the OUI 9C:9E:03?

9C:9E:03 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to awayfrom. It covers every address from 9C:9E:03:00:00:00 to 9C:9E:03:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-9E-03.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 9C:9E:03:00:00:00 that is 9C:9E:03 — 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 awayfrom located?

awayfrom is listed at A-2723 Ho, Sambo Techon Tower,122,jomaru-ro 385 Beon-gil bucheon-si Gyeonnggi-do KR 14556 in the IEEE OUI registry entry for 9C:9E:03. This is the address the organization registered with the IEEE, which may differ from its current operating address.
