Which company owns MAC address prefix 00:0F:65?

MAC address prefix 00:0F:65 is registered to icube Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0F:65 has a network interface built by icube Corp..

What is the OUI 00:0F:65?

00:0F:65 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to icube Corp.. It covers every address from 00:0F:65:00:00:00 to 00:0F:65:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0F-65.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0F:65:00:00:00 that is 00:0F:65 — 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 icube Corp. located?

icube Corp. is listed at Olympia Center 2F,828-10,Yeoksam-dong,Kangnam-ku Seoul South KR 135-935 in the IEEE OUI registry entry for 00:0F:65. This is the address the organization registered with the IEEE, which may differ from its current operating address.
