What Is DNS and Why Does It Matter?
The Domain Name System translates website names (like google.com) into IP addresses that computers use to connect. By default, your ISP handles all DNS requests — meaning they can see every website you visit, even if the connection is otherwise encrypted. A virtual private network routes DNS requests through its own private DNS servers, preventing ISP tracking.
DNS Leaks — The Hidden Privacy Threat
A DNS leak occurs when DNS queries bypass the private network tunnel and go directly to your ISP DNS servers. This can happen due to misconfiguration, IPv6 conflicts, or Windows DNS settings. DNS leaks expose your browsing history to your ISP even though you are connected to a private network. Regular leak testing is essential.
