Which company owns MAC address prefix 08:00:59?

MAC address prefix 08:00:59 is registered to A/S MYCRON in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:00:59 has a network interface built by A/S MYCRON.

What is the OUI 08:00:59?

08:00:59 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to A/S MYCRON. It covers every address from 08:00:59:00:00:00 to 08:00:59:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-00-59.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:00:59:00:00:00 that is 08:00:59 — 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 A/S MYCRON located?

A/S MYCRON is listed at PO BOX 6199 NO in the IEEE OUI registry entry for 08:00:59. This is the address the organization registered with the IEEE, which may differ from its current operating address.
