Which company owns MAC address prefix 18:F1:45?

MAC address prefix 18:F1:45 is registered to NetComm Wireless Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:F1:45 has a network interface built by NetComm Wireless Limited.

What is the OUI 18:F1:45?

18:F1:45 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NetComm Wireless Limited. It covers every address from 18:F1:45:00:00:00 to 18:F1:45:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-F1-45.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:F1:45:00:00:00 that is 18:F1:45 — 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 NetComm Wireless Limited located?

NetComm Wireless Limited is listed at Level 2, 18-20 Orion Road Lane Cove Sydney AU 2066 in the IEEE OUI registry entry for 18:F1:45. This is the address the organization registered with the IEEE, which may differ from its current operating address.
