What is a “DNS leak” and how can I protect myself?

What does DNS mean anyway?

DOMain Nsoul Server. All internet users use DNS. Each device worldwide has its own, exact IP address. (Ex .: Without the IP, communication between the devices would not be possible. For this reason, web pages also have their own IP addresses, which theoretically could be used to reach them. (Ex: https: // /) Since it is much easier to remember a domain name instead of a long number, you use names like www.vpntester.de. However, to be able to establish a connection between the domain name and the IP address, you need DNS services / servers. So every time you call a website, a DNS service is queried for the destination IP address.
