Which company owns MAC address prefix 4C:11:59?

MAC address prefix 4C:11:59 is registered to Vision Information & Communications in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 4C:11:59 has a network interface built by Vision Information & Communications.

What is the OUI 4C:11:59?

4C:11:59 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Vision Information & Communications. It covers every address from 4C:11:59:00:00:00 to 4C:11:59:FF:FF:FF, or 16,777,216 addresses in total. It is also written 4C-11-59.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 4C:11:59:00:00:00 that is 4C:11:59 — 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 Vision Information & Communications located?

Vision Information & Communications is listed at 151, Ulseong-gil Pyeongtaek-si Gyeonggi-do KR 17823 in the IEEE OUI registry entry for 4C:11:59. This is the address the organization registered with the IEEE, which may differ from its current operating address.
