What is a DNS Leak?

DNS acts like a phonebook, translating website names (like google.com) into IP addresses. If your browser bypasses the encrypted VPN tunnel to ask your local ISP's DNS servers instead of VPN Duo's secure resolvers, your ISP can still log every site you visit. VPN Duo forces all DNS queries through our secure tunnel to prevent this tracking.
