Which company owns MAC address prefix 00:03:13?

MAC address prefix 00:03:13 is registered to Access Media SPA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:03:13 has a network interface built by Access Media SPA.

What is the OUI 00:03:13?

00:03:13 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Access Media SPA. It covers every address from 00:03:13:00:00:00 to 00:03:13:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-03-13.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:03:13:00:00:00 that is 00:03:13 — 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 Access Media SPA located?

Access Media SPA is listed at Via delle Industrie, 4/g 24035 LALLIO (BG) IT in the IEEE OUI registry entry for 00:03:13. This is the address the organization registered with the IEEE, which may differ from its current operating address.
