Before we delve into how to conduct a DNS leak check, it’s important to understand what a DNS leak is. In simple terms, a DNS leak occurs when your DNS requests are exposed to your Internet Service Provider (ISP) despite using a Virtual Private Network (VPN). This can compromise your online privacy, revealing the websites you visit even when you’re trying to mask your activity.

Recognizing a DNS leak is essential for anyone concerned about online privacy. Here are some reasons why performing a DNS leak check is vital:
- Maintains Privacy: Keeps your browsing activities confidential.
- Prevents Surveillance: Stops ISPs from tracking your online movements.
- Enhances Security: Mitigates risks of cyber-attacks that could exploit DNS vulnerabilities.
How to Perform a DNS Leak Check
Conducting a DNS leak check is relatively simple. Follow these steps to ensure your DNS queries are secure:
