Which company owns MAC address prefix 18:B1:69?

MAC address prefix 18:B1:69 is registered to Sonicwall in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:B1:69 has a network interface built by Sonicwall.

What is the OUI 18:B1:69?

18:B1:69 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sonicwall. It covers every address from 18:B1:69:00:00:00 to 18:B1:69:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-B1-69.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:B1:69:00:00:00 that is 18:B1:69 — 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 Sonicwall located?

Sonicwall is listed at 2001 Logic Drive San Jose CA US 95124-3452 in the IEEE OUI registry entry for 18:B1:69. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Sonicwall own?

Sonicwall holds 3 OUI prefixes in the IEEE registry, of which 18:B1:69 is one. A device made by Sonicwall could carry a MAC address from any of them.
