Without the domain name system, surfing on the internet would be much more difficult, as we would have to memorize a lot of IP addresses. With the help of DNS servers, we can instead use a memorable domain name to access our favorite website. Find out how you can set up your own DNS server and learn more about the basics of the World Wide Web. All you need is the minicomputer Raspberry Pi and an...How to set up your own DNS server with Raspberry Pi
Operating systems, such as Windows or macOS, automatically save information about address resolution from systems and applications in the network in a DNS cache. The purpose of this practical cache is to speed up network traffic. Read on to find out why it’s useful to regularly clear the DNS cache and how exactly such a DNS flush works.Flush DNS | How to clear the DNS Cache

DNS resolvers are a core component of the DNS, and therefore one of the cornerstones of the internet. For the most part, however, the resolvers work in secret. The importance of DNS resolvers only becomes apparent when the connection to websites and mail servers breaks down. Our article explains how to proceed and how the technology works in detail.What is a DNS resolver?
Translating domain names to IP addresses is one of the central services on the internet. Your computer sends daily requests to the domain name system (DNS) without you knowing. Name resolution on the internet usually only captures our attention when something isn’t working properly. But ask yourself today: What is DNS? And what is a DNS server?DNS – the internet naming system

If you change the DNS of a website, it can take hours or even days for the changes to reach each server. This transition phase is called DNS propagation. Our article shows you what it is, where the delay comes from, and how you can easily test DNS propagation.What is DNS propagation?
Operating systems tend to collect various information on user surfing behavior on the World Wide Web in a so-called DNS cache. First and foremost, this cache gives a good overview of your web history. However, the stored entries can also cause connection problems. We will show you how to clear the DNS cache (as a user of Windows, Mac, or Linux).Clear DNS cache: how to empty the DNS resolver cache
