Raspberry Pi is an inexpensive micro-computer that can behave like a standard computer in many respects. The innovative mini device can be used for a wide range of tasks - from setting up an operating system to surfing the web, to using it as a server or a media center. Discover these interesting Raspberry Pi projects to try out at home.
DNS spoofing involves tampering with DNS name resolution. This kind of attack poses a serious threat to internet users. Here you will learn how the different types of attack methods work, which targets attackers go after, and what you can do to effectively protect yourself.
Many Internet users have a basic idea of what the term “domain” refers to. After all, domains are abundant on the Internet via URLs. If you delve deeper into the subject, though, it quickly becomes confusing. “Name server,” “DNS zone,” “zone file”: What do these terms mean, and how are the concepts related? We’ll shed some light on the topic here.
Are you concerned about maintaining your privacy and use a VPN when surfing? Great – but this can make you uniquely vulnerable, too. We will show you the dangers posed by DNS leaks and explain how you can effectively protect yourself against them. In the process, we also look at DNS leak testers.
The DNS is one of the cornerstones of the Internet. To ensure that the resolution of domain names into IP addresses works reliably, the information of a DNS zone is stored redundantly all over the world.

Spam has been around since the dawn of email. Whether you’re dealing with annoying junk mail or emails containing dangerous malware, having a strong anti-spam system is essential. DNS-based blackhole lists (DNSBL) are a key part of most anti-spam technologies. Keep reading to find out what DNSBL are and how they work.
For many years, dedicated IPs were an important component within hosting and mailing. To this day, you can choose a dedicated IP address for your project from a wide variety of services. But is a dedicated IP really a better solution than a shared address? We’ll show you what you need to know about the two IP types and dispel common myths.
Various operating systems, such as Windows or macOS, automatically save information about address resolution from systems and applications in the network in a DNS cache. For Linux there are also corresponding services, though they have to be installed by the user. The purpose of this practical cache is to speed up network traffic, which is particularly important on the internet. Why it’s useful to...
Without the Domain Name System, users of the World Wide Web would have serious problems when trying to load websites and other online presences. It’s only thanks to this system that internet addresses appear in their trusted text format: they’re actually nothing more than combinations of numbers. The communication between browser and name server responsible for this isn’t actually as secure as you...
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...
