Which company owns MAC address prefix 18:06:F5?

MAC address prefix 18:06:F5 is registered to RAD Data Communications, Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:06:F5 has a network interface built by RAD Data Communications, Ltd..

What is the OUI 18:06:F5?

18:06:F5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to RAD Data Communications, Ltd.. It covers every address from 18:06:F5:00:00:00 to 18:06:F5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-06-F5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:06:F5:00:00:00 that is 18:06:F5 — 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 RAD Data Communications, Ltd. located?

RAD Data Communications, Ltd. is listed at 24 Raoul Wallenberg St. Tel Aviv IL 69719 in the IEEE OUI registry entry for 18:06:F5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
