DNS over TLS (DoT) encrypts your DNS queries, ensuring your ISP and hackers can't see your browsing activity. For example, instead of sending plain text requests that can be intercepted, DoT wraps them in a secure TLS layer, keeping your data private and protected. 

TLS itself consists of several layers:
1. **Record Layer**: Ensures data integrity and confidentiality by fragmenting data into manageable blocks, compressing, and encrypting them.
2. **Handshake Protocol**: Manages the negotiation between client and server to establish a secure connection, including authentication and session key exchange.
3. **Alert Protocol**: Handles errors and alerts during the communication, such as warnings or fatal errors.
4. **Change Cipher Spec Protocol**: Signals the transition to a secure state after the handshake is complete.
