Which company owns MAC address prefix 48:AA:5D?

MAC address prefix 48:AA:5D is registered to Store Electronic Systems in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:AA:5D has a network interface built by Store Electronic Systems.

What is the OUI 48:AA:5D?

48:AA:5D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Store Electronic Systems. It covers every address from 48:AA:5D:00:00:00 to 48:AA:5D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-AA-5D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:AA:5D:00:00:00 that is 48:AA:5D — 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 Store Electronic Systems located?

Store Electronic Systems is listed at 39 rue de montigny Argenteuil FR 95100 in the IEEE OUI registry entry for 48:AA:5D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
