Which company owns MAC address prefix 70:8B:97?

What is the OUI 70:8B:97?

70:8B:97 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to INSYS icom GmbH. It covers every address from 70:8B:97:00:00:00 to 70:8B:97:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-8B-97.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:8B:97:00:00:00 that is 70:8B:97 — 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 INSYS icom GmbH located?

INSYS icom GmbH is listed at Hermann-Köhl-Str. 22 Regensburg DE 93049 in the IEEE OUI registry entry for 70:8B:97. This is the address the organization registered with the IEEE, which may differ from its current operating address.
