Which company owns MAC address prefix C0:F9:91?

MAC address prefix C0:F9:91 is registered to GME Standard Communications P/L in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:F9:91 has a network interface built by GME Standard Communications P/L.

What is the OUI C0:F9:91?

C0:F9:91 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GME Standard Communications P/L. It covers every address from C0:F9:91:00:00:00 to C0:F9:91:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-F9-91.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:F9:91:00:00:00 that is C0:F9:91 — 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 GME Standard Communications P/L located?

GME Standard Communications P/L is listed at 17 Gibbon Rd. Winston Hills New South Wales AU 2153 in the IEEE OUI registry entry for C0:F9:91. This is the address the organization registered with the IEEE, which may differ from its current operating address.
