Which company owns MAC address prefix 7C:78:B2?

MAC address prefix 7C:78:B2 is registered to Wyze Labs Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 7C:78:B2 has a network interface built by Wyze Labs Inc.

What is the OUI 7C:78:B2?

7C:78:B2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Wyze Labs Inc. It covers every address from 7C:78:B2:00:00:00 to 7C:78:B2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-78-B2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:78:B2:00:00:00 that is 7C:78:B2 — 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 Wyze Labs Inc located?

Wyze Labs Inc is listed at 4030 Lake Washington Boulevard NE Kirkland WA US 98033 in the IEEE OUI registry entry for 7C:78:B2. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Wyze Labs Inc own?

Wyze Labs Inc holds 5 OUI prefixes in the IEEE registry, of which 7C:78:B2 is one. A device made by Wyze Labs Inc could carry a MAC address from any of them.
