Which company owns MAC address prefix 00:08:65?

MAC address prefix 00:08:65 is registered to JASCOM CO., LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:08:65 has a network interface built by JASCOM CO., LTD.

What is the OUI 00:08:65?

00:08:65 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JASCOM CO., LTD. It covers every address from 00:08:65:00:00:00 to 00:08:65:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-08-65.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:08:65:00:00:00 that is 00:08:65 — 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 JASCOM CO., LTD located?

JASCOM CO., LTD is listed at JUAN INDUSTRIAL COMPLEX 330, 17-1, JUAN-DONG NAM-GU INCHEON KR 402-200 in the IEEE OUI registry entry for 00:08:65. This is the address the organization registered with the IEEE, which may differ from its current operating address.
