Which company owns MAC address prefix EC:46:70?

MAC address prefix EC:46:70 is registered to Meinberg Funkuhren GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:46:70 has a network interface built by Meinberg Funkuhren GmbH & Co. KG.

What is the OUI EC:46:70?

EC:46:70 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Meinberg Funkuhren GmbH & Co. KG. It covers every address from EC:46:70:00:00:00 to EC:46:70:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-46-70.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:46:70:00:00:00 that is EC:46:70 — 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 Meinberg Funkuhren GmbH & Co. KG located?

Meinberg Funkuhren GmbH & Co. KG is listed at Lange Wand 9 Bad Pyrmont NDS DE 31812 in the IEEE OUI registry entry for EC:46:70. This is the address the organization registered with the IEEE, which may differ from its current operating address.
