What is the OUI 00:18:49?

00:18:49 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to nVent, Schroff GmbH. It covers every address from 00:18:49:00:00:00 to 00:18:49:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-18-49.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:18:49:00:00:00 that is 00:18:49 — 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 nVent, Schroff GmbH located?

nVent, Schroff GmbH is listed at Langenalber Strasse 96-100 Straubenhardt DE 75334 in the IEEE OUI registry entry for 00:18:49. This is the address the organization registered with the IEEE, which may differ from its current operating address.
