Which company owns MAC address prefix 30:AC:ED?

MAC address prefix 30:AC:ED is registered to Packet Clearing House in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:AC:ED has a network interface built by Packet Clearing House.

What is the OUI 30:AC:ED?

30:AC:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Packet Clearing House. It covers every address from 30:AC:ED:00:00:00 to 30:AC:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-AC-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:AC:ED:00:00:00 that is 30:AC: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 Packet Clearing House located?

Packet Clearing House is listed at 49 Boulevard de La Tour-Maubourg Paris Paris FR 75007 in the IEEE OUI registry entry for 30:AC:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
