What is the OUI A0:22:52?

A0:22:52 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Astra Wireless Technology FZ-LLC. It covers every address from A0:22:52:00:00:00 to A0:22:52:FF:FF:FF, or 16,777,216 addresses in total. It is also written A0-22-52.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A0:22:52:00:00:00 that is A0:22:52 — 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 Astra Wireless Technology FZ-LLC located?

Astra Wireless Technology FZ-LLC is listed at T1-4F-63, RAKEZ Amenity Center, Al Hamra Industrial Zone-FZ Ras Al Khaimah AE 7100 in the IEEE OUI registry entry for A0:22:52. This is the address the organization registered with the IEEE, which may differ from its current operating address.
