What is DNS?
DNS or the domain name system is used to translate domain names such as www.astrill.com into a numerical IP addresses, e.g. 188.8.131.52 which are required to route packets of data on the Internet. Whenever your computer needs to contact a server on the Internet, such as when you enter a URL into your browser, your computer contacts a DNS server and requests the IP address. Most Internet service providers assign their customers a DNS server which they control and use for logging and recording your Internet activities.
How can DNS leak?
When your operating system, even while connected to an anonymous network, continues to use its default DNS servers instead of the anonymous DNS servers assigned to your computer, it results in DNS leaks. These leaks compromise the effectiveness of the anonymous network and pose a significant threat to your privacy. Despite relying on the anonymous network for security, your private data is exposed, revealing a false sense of security. It is important to address DNS leaks to mitigate the risks associated with compromised privacy.
Why should I care?
DNS leaks can seriously impact your privacy and security. Even though they don't capture your website data, they reveal which websites you visit, allowing others to track your online activities and compromise your privacy. DNS leaks also open the door to DNS poisoning attacks, where attackers manipulate DNS responses and direct you to fake websites for phishing attempts. Addressing DNS leaks to protect your privacy and enhance your overall cybersecurity is crucial.
