Which company owns MAC address prefix 44:83:12?

MAC address prefix 44:83:12 is registered to Star-Net in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:83:12 has a network interface built by Star-Net.

What is the OUI 44:83:12?

44:83:12 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Star-Net. It covers every address from 44:83:12:00:00:00 to 44:83:12:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-83-12.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:83:12:00:00:00 that is 44:83:12 — 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 Star-Net located?

Star-Net is listed at Egoz 64 Kiryat Byalik Israel IL 27000 in the IEEE OUI registry entry for 44:83:12. This is the address the organization registered with the IEEE, which may differ from its current operating address.
