Prevent DNS leaks!

Whoever runs your DNS servers can log every website you visit.
Every time you enter an address in your browser, such as https://www.spyoff.com, your computer sends a request to a so-called "DNS server". A DNS server is a directory of which address belongs to which IP. Similar to a phone book. The DNS server then sends the number of the server hosting the website to your computer. Your computer then connects to this address.
Of course, through these requests, the DNS server knows exactly which pages you want to visit or which applications you use. Now if the operator of your DNS server stores your requests, he has a very accurate picture of your surfing behavior including your personal IP address.
A so-called DNS leak occurs when you connect to a VPN, but your computer continues to use its normal DNS server to resolve addresses. So while your connection to the site is encrypted, the operator of your DNS still knows which pages you connect to. To detect such problems, we provide you a DNS leak test, which shows you exactly if you are suffering from this problem.
So before you surf the web with your VPN, you should always do a DNS leak test to make sure that you are fully protected!
