What is the OUI D4:11:D6?

D4:11:D6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ShotSpotter, Inc.. It covers every address from D4:11:D6:00:00:00 to D4:11:D6:FF:FF:FF, or 16,777,216 addresses in total. It is also written D4-11-D6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:11:D6:00:00:00 that is D4:11:D6 — 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 ShotSpotter, Inc. located?

ShotSpotter, Inc. is listed at 1060 Terra Bella Ave. Mountain View CA US 94043 in the IEEE OUI registry entry for D4:11:D6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
