Wollen Sie den DNS-Server aus einem der genannten Gründe oder testweise auf Ihrem Gerät ändern, können Sie das problemlos und ohne großen Aufwand über die Netzwerkeinstellungen des jeweiligen Systems selbst erledigen. Natürlich unterscheiden sich die notwendigen Schritte dabei voneinander – unter Windows werden DNS-Server-Änderungen zum Beispiel anders vorgenommen als auf dem Mac oder einem Android-Gerät. Wir geben Ihnen daher Kurzanleitungen für den DNS-Server-Wechsel auf verschiedenen Plattformen wie Windows 10, macOS, Linux (Ubuntu) oder iOS.

Verschlüsseltes DNS (DoT) mit der FritzBox nutzen
(1. November 2020)
Unverschlüsselte DNS-Anfragen sind eine potentielle Gefahr für die Privatsphäre und bieten einen einfachen Angriffspunkt für Manipulation.
Derzeit kämpfen zwei konkurrierende Standards darum, diese Probleme zu beheben. DoT (DNS-over-TLS) und DoH (DNS-over-HTTPS). AVM hat sich entschieden mit den FritzBox-Routern DoT zu unterstützen. Seit Firmware 7.20 ist diese Option verfügbar.

What Is DNS Security? Why It Matters for Your Business
(02.09.2022)
In 2022 and beyond, the industry and society have matured, and we’re now focusing on security suites and infrastructure unification, as well as managing cyber risks. The opportunities and driving factors of one decade do not take the place of those in the one before it.
Instead, they broaden the perspective and emphasize well-known ideas in new ways. One such example is DNS – although its roots can be traced back to 1966, DNS security must be a part of every robust cybersecurity strategy today.

Open DNSSEC Validating Resolvers
What is the CZ.NIC ODVR?
CZ.NIC ODVR are Open DNSSEC Validating Resolvers that you might freely use instead of the standard DNS resolvers offered by your Internet service provider.
What is DNS?
DNS (Domain Name System) acts like a phone directory for the internet IP addresses. It pairs the numeric IP addresses with labels, called domain names, that a user can easily remember and type in their web browser (e.g., if they look for a company called XYZ, they type in www.xyz.com). Just like a phone, the browser then searches the „directory“, looks up the right record, automatically connects to an IP address assigned to that domain name and finally displays the company’s webpage to the user.
More information is on the page About domains and DNS.
What is DNSSEC?
DNSSEC is an extension to the Domain Name System (DNS) that enhances its security. DNSSEC guarantees its users that the information they have received from DNS was provided by a right source, is complete and its integrity has not been tampered with. DNSSEC ensures the credibility of DNS information.
More information can be found on the page How DNSSEC works.
How to setup CZ.NIC resolvers?
Change your network configuration so that it uses resolvers with IP addresses 193.17.47.1 and 185.43.135.1.
(…)
You can verify the correctness of your setting via the test bellow.
Configure your server for the public DNS resolver
The public DNS resolver must be manually configured either at the system level (for DNS-over-TLS) or at the browser level (for DNS-over-HTTPS) according to the following information:
Server name: kaitain.restena.lu
IPv4 address: 158.64.1.29
IPv6 address: 2001:a18:1::29
Port (DNS-over-TLS): 853

– 185.95.218.42
– 185.95.218.43
Öffentliche DNS-Resolver
Die DNS-Resolver sind so konfiguriert, dass sie die Privatsphäre möglichst gut schützen und einen freien Zugang zum Internet gewähren. Es findet kein Logging statt und es werden keine Sperrlisten verwendet. DNSSEC wird validiert.

Simple DNSCrypt: DNS-Abfragen unter Windows verschlüsseln
(05.02.2021)
Bereits 2017 hat der Informatiker Dominik Herrmann in seiner Dissertation „Das Internet-Adressbuch bedroht unsere Privatsphäre“ (PDF) nachgewiesen, wie anhand von unverschlüsselten DNS-Abfragen, die Identität eines Internetnutzers ermittelt werden kann. Herrmann sieht eine Zentralisierung der Namensauflösung für die internationale Konzerne wie Google, OpenDNS und Symantec verantwortlich seien. „Im Jahr 2016 beantworteten allein die DNS-Server von Google schon mehr als 13 Prozent aller DNS-Anfragen pro Tag.“
5 Encrypted DNS Services to Use on iOS and macOS
Short for Domain Name System, DNS is commonly referred to as the “phone book” of the internet. It helps connect web browsers with web servers by translating addresses like 104.26.0.124 into www.macobserver.com. Here are five encrypted DNS services that I recommend.
There are several different ways to use a DNS server. One is to manually go into network settings on each and configure the Wi-Fi. The second way is to download an app, and the third way is to go into your router settings and configure it there.

DNSSEC Schutz für das Internet
DNSSEC ist ein Protokoll, das gegenwärtig zur Sicherung des Domain-namensystems (DNS), also dem weltweiten Telefonbuch des Internets, implementiert wird. Normale Benutzer rufen Internetserver lieber mithilfe konkreter Bezeichnungen auf (beispielsweise icann.org) – hinter den Kulissen jedoch bildet das DNS jeden Namen auf eine numerische Adresse ab, um die Daten an das korrekte Gerät zu übertragen. DNSSEC ist die Abkürzung für „DNS Security Extensions“, also DNS-Sicherheitserweiterungen. DNSSEC ergänzt das DNS um Sicherheits-funktionen, indem eine Verschlüsselungsmethodik basierend auf öffentlichen Schlüsseln in die DNS-Hierarchie integriert wird. Dadurch entsteht eine einzelne, offene und globale Public-Key-Infrastruktur (PKI) für Domainnamen. Dies ist das Ergebnis einer mehr als zehnjährigen Entwicklung offener Standards innerhalb der Nutzergemeinschaft.

Spoofing: Neue DNS-Angriffsmethode entdeckt
(13. November 2020)
Nachdem der Quellport de-randomisiert worden sei, sei es möglich gewesen, eine böswillige IP-Adresse einzuschleusen und so erfolgreich einen DNS-Cache-Poisoning-Angriff durchzuführen. Die Details haben die Forscher im Paper „DNS Cache Poisoning Attack Reloaded: Revolutions with Side Channels“ publiziert.
Weitere Experimente unter realistischen Serverkonfigurationen und Netzwerkbedingungen würden zudem zeigen, dass ihre grundlegende Methode leicht an das gesamte DNS-System angepasst werden könnte.
SAD Reality for DNS
The researchers determined that 35% of open resolvers are open to the attack, as well as four of six home routers made by well-known brands.
They also found that 12 of 14 popular public resolvers (now 11—Cloudflare says they’ve corrected their systems) are susceptible. Even a patched DNS server could be made vulnerable by an unpatched or misconfigured NAT gateway.
Their 19-page paper on the exploit includes lists of devices and services tested. They have since set up a SAD DNS website featuring a Q&A and a tool that anyone can use to determine whether their DNS is vulnerable.
The flaw is being tracked as CVE-2020-25705, and affects Linux 3.18 – 5.10, Windows Server 2019 version 1809 and newer, macOS 10.15 and newer, and FreeBSD 12.1.0 and newer. The researchers did not test earlier versions of the listed operating system.
DNSViz is a tool for visualizing the status of a DNS zone. It was designed as a resource for understanding and troubleshooting deployment of the DNS Security Extensions (DNSSEC).
It provides a visual analysis of the DNSSEC authentication chain for a domain name and its resolution path in the DNS namespace, and it lists configuration errors detected by the tool.
DNSSEC – What Is It and Why Is It Important?
DNS data for a domain is called a zone. Some organizations operate their own name servers to publish their zones, but usually organizations outsource this function to third parties. There are different types of organizations that host DNS zones on behalf of others, including registrars, registries, web hosting companies, network server providers, just to name a few.
DNS by itself is not secure
DNS was designed in the 1980s when the Internet was much smaller, and security was not a primary consideration in its design. As a result, when a recursive resolver sends a query to an authoritative name server, the resolver has no way to verify the authenticity of the response.
