Which company owns MAC address prefix 58:1F:19?

MAC address prefix 58:1F:19 is registered to EMH Metering GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:1F:19 has a network interface built by EMH Metering GmbH & Co. KG.

What is the OUI 58:1F:19?

58:1F:19 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EMH Metering GmbH & Co. KG. It covers every address from 58:1F:19:00:00:00 to 58:1F:19:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-1F-19.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:1F:19:00:00:00 that is 58:1F:19 — 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 EMH Metering GmbH & Co. KG located?

EMH Metering GmbH & Co. KG is listed at Neu- Galliner Weg 1 Gallin DE 19258 in the IEEE OUI registry entry for 58:1F:19. This is the address the organization registered with the IEEE, which may differ from its current operating address.
