Which company owns MAC address prefix E0:64:BB?

MAC address prefix E0:64:BB is registered to DigiView S.r.l. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:64:BB has a network interface built by DigiView S.r.l..

What is the OUI E0:64:BB?

E0:64:BB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DigiView S.r.l.. It covers every address from E0:64:BB:00:00:00 to E0:64:BB:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-64-BB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:64:BB:00:00:00 that is E0:64:BB — 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 DigiView S.r.l. located?

DigiView S.r.l. is listed at Via Senigallia 18/2 Milano IT 20161 in the IEEE OUI registry entry for E0:64:BB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
