Which company owns MAC address prefix 58:E8:08?

MAC address prefix 58:E8:08 is registered to AUTONICS CORPORATION in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:E8:08 has a network interface built by AUTONICS CORPORATION.

What is the OUI 58:E8:08?

58:E8:08 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AUTONICS CORPORATION. It covers every address from 58:E8:08:00:00:00 to 58:E8:08:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-E8-08.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:E8:08:00:00:00 that is 58:E8:08 — 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 AUTONICS CORPORATION located?

AUTONICS CORPORATION is listed at 41-5 YONGDANG-DONG YANGSAN-SI KYEONGNAM KR 626-847 in the IEEE OUI registry entry for 58:E8:08. This is the address the organization registered with the IEEE, which may differ from its current operating address.
