Which company owns MAC address prefix 34:0C:ED?

MAC address prefix 34:0C:ED is registered to Moduel AB in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 34:0C:ED has a network interface built by Moduel AB.

What is the OUI 34:0C:ED?

34:0C:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Moduel AB. It covers every address from 34:0C:ED:00:00:00 to 34:0C:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-0C-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:0C:ED:00:00:00 that is 34:0C:ED — 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 Moduel AB located?

Moduel AB is listed at Hudiksvallsgatan 8 Stockholm Stockholm SE 11330 in the IEEE OUI registry entry for 34:0C:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
