What is the OUI 74:53:A8?

74:53:A8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ACL Airshop BV. It covers every address from 74:53:A8:00:00:00 to 74:53:A8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-53-A8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:53:A8:00:00:00 that is 74:53:A8 — 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 ACL Airshop BV located?

ACL Airshop BV is listed at Kantoorweg 7 West Knollendam NH NL 1525 RJ in the IEEE OUI registry entry for 74:53:A8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
