Which company owns MAC address prefix A8:C0:EA?

MAC address prefix A8:C0:EA is registered to Pepwave Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:C0:EA has a network interface built by Pepwave Limited.

What is the OUI A8:C0:EA?

A8:C0:EA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Pepwave Limited. It covers every address from A8:C0:EA:00:00:00 to A8:C0:EA:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-C0-EA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:C0:EA:00:00:00 that is A8:C0:EA — 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 Pepwave Limited located?

Pepwave Limited is listed at A5, 5/F, HK Spinners Industrial Building, Phase 6, 481 Castle Peak Road Cheung Sha Wan Hong Kong HK 0 in the IEEE OUI registry entry for A8:C0:EA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
