Which company owns MAC address prefix 88:D1:71?

MAC address prefix 88:D1:71 is registered to BEGHELLI S.P.A in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:D1:71 has a network interface built by BEGHELLI S.P.A.

What is the OUI 88:D1:71?

88:D1:71 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BEGHELLI S.P.A. It covers every address from 88:D1:71:00:00:00 to 88:D1:71:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-D1-71.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:D1:71:00:00:00 that is 88:D1:71 — 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 BEGHELLI S.P.A located?

BEGHELLI S.P.A is listed at VIA MOZZEGHINE 13/15 LOCALITA' MONTEVEGLIO - COMUNE VALSAMOGGIA BOLOGNA IT 40053 in the IEEE OUI registry entry for 88:D1:71. This is the address the organization registered with the IEEE, which may differ from its current operating address.
