Which company owns MAC address prefix 10:27:79?

MAC address prefix 10:27:79 is registered to Sadel S.p.A. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:27:79 has a network interface built by Sadel S.p.A..

What is the OUI 10:27:79?

10:27:79 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sadel S.p.A.. It covers every address from 10:27:79:00:00:00 to 10:27:79:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-27-79.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:27:79:00:00:00 that is 10:27:79 — 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.
