Who owns the MAC starting with CC:45:A5?
The first three blocks of a MAC address form the OUI (Organizationally Unique Identifier), a code the IEEE assigns to each manufacturer. The prefix CC:45:A5 is registered to Texas Instruments. Any device whose MAC starts with CC:45:A5 (for example, CC:45:A5:1A:2B:3C) was made by this company.
What it means to see this device on your network
Knowing the manufacturer helps identify what is connected to your Wi-Fi or company network. A Texas Instruments MAC you don't recognize could be a legitimate device (a phone, a TV, a camera) — or one that shouldn't be there. Texas Instruments has 401 MAC prefixes registered with the IEEE (see others under "Read also").
