Description: DNS leak is a security flaw that occurs when a VPN (Virtual Private Network) does not adequately protect a user’s DNS (Domain Name System) requests. This means that even though the user’s internet traffic is encrypted and routed through a VPN server, DNS requests may be sent to the internet service provider’s (ISP) DNS servers instead of being handled by the VPN. As a result, the user’s online activity can be exposed, allowing the ISP and other malicious actors to track the websites visited. DNS leaks can occur for various reasons, such as incorrect VPN configurations, software failures, or compatibility issues with the operating system. The relevance of this issue lies in the growing concern for online privacy and the need to protect users’ personal information. To mitigate this risk, many VPN providers implement DNS leak protection features, ensuring that all DNS requests are securely and privately handled through their own servers, helping to maintain the confidentiality of the user’s online activity.
