Which company owns MAC address prefix 70:9A:0B?

MAC address prefix 70:9A:0B is registered to Italian Institute of Technology in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:9A:0B has a network interface built by Italian Institute of Technology.

What is the OUI 70:9A:0B?

70:9A:0B is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Italian Institute of Technology. It covers every address from 70:9A:0B:00:00:00 to 70:9A:0B:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-9A-0B.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:9A:0B:00:00:00 that is 70:9A:0B — 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 Italian Institute of Technology located?

Italian Institute of Technology is listed at Via Morego 30 Genova GE IT 16163 in the IEEE OUI registry entry for 70:9A:0B. This is the address the organization registered with the IEEE, which may differ from its current operating address.
