Which company owns MAC address prefix 74:57:98?

MAC address prefix 74:57:98 is registered to TRUMPF Laser GmbH + Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:57:98 has a network interface built by TRUMPF Laser GmbH + Co. KG.

What is the OUI 74:57:98?

74:57:98 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TRUMPF Laser GmbH + Co. KG. It covers every address from 74:57:98:00:00:00 to 74:57:98:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-57-98.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:57:98:00:00:00 that is 74:57:98 — 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 TRUMPF Laser GmbH + Co. KG located?

TRUMPF Laser GmbH + Co. KG is listed at Aichhalder Str. 39 Schramberg BW DE 78713 in the IEEE OUI registry entry for 74:57:98. This is the address the organization registered with the IEEE, which may differ from its current operating address.
