DoT (DNS over TLS) is a protocol that encrypts DNS queries using TLS (Transport Layer Security). It allows name service queries to travel over a separate, encrypted connection, preventing outsiders from seeing what websites a user is trying to access. DoT uses port 853 and provides strong privacy protection, especially on mobile devices and routers.

By default, your home network likely relies on a DNS server provided by your internet provider. However, these servers aren’t always the fastest and, in some cases, may even allow your ISP to maliciously track your online behavior. To that end, if internet speed and privacy matter a lot, you should perhaps consider changing your DNS server.
The best way to change your DNS server is at the router level, which will affect every single device connected to it.

Quantum processors can evaluate many possible solutions in parallel rather than sequentially. This capability has profound implications for cryptography. Today’s most widely deployed encryption schemes, RSA and elliptic curve cryptography (ECC), can be broken and rendered obsolete by a quantum computer.
Everything from industrial IoT sensors and automotive control systems to cloud infrastructure and secure boot mechanisms relies on RSA or ECC for encryption today. When quantum computers reach the scale required to break these algorithms, that entire trust architecture collapses simultaneously.
Compounding the urgency is an attack vector already in use: Harvest now, decrypt later.

A Domain Name System (DNS) matches human-friendly domain names to computer-friendly IP addresses.
When you type in a domain name like cyberghost.com, for example, your web browser sends the request to your ISP via your router. Your ISP refers the request to its default DNS server. The DNS server then supplies the relevant IP address so your browser can load the appropriate page.
A DNS also saves a local copy or cache of sites you’ve recently visited on your device for quick and easy reference.
It seems like a streamlined service; what could go wrong? Check the following reasons why you should change your DNS.
Incorrect network configurations or faulty VPN/proxy software can lead to your device sending DNS requests directly to your ISP‘s server, potentially enabling ISPs or other third parties to monitor your online activity.
The DNS Leak Test is a tool used to determine which DNS servers your browser is using to resolve domain names. This test attempts to resolve 50 randomly generated domain names, of which 25 are IPv4-only and 25 are IPv6-only.

Everyone is equal on the Internet; at least that’s what many people optimistically thought at the beginning of the millennium. When it gradually found its way in the late 1950s from military think tanks into academia and then initially a small public sphere, the Internet was considered a utopia. Hidden behind the mask of anonymity, all users would be equal and therefore would all have equal rights. There would be no hierarchies – not even among users in different countries.
Yet this hope that the Internet would be a non-discriminatory space remains an illusion to this day. Quite to the contrary, power structures are already firmly established in its technical infrastructure. They continue the history of colonialism in the virtual sphere in the form of “digital” or “electronic colonialism.”

Im Internet sind alle gleich, so dachten noch zu Beginn des Millenniums viele Menschen hoffnungsvoll. Als es Ende der 1950er-Jahre von militärischen Thinktanks aus nach und nach in die Wissenschaft und eine zunächst noch kleine Öffentlichkeit fand, glich das Internet einer Utopie. Hinter der Maske der Anonymität sollten alle Nutzer*innen gleich sein und somit alle die gleichen Rechte haben. Keine Hierarchien – auch nicht zwischen den User*innen in verschiedenen Ländern.
Doch diese Hoffnung vom Internet als einem diskriminierungsfreien Raum bleibt bis heute eine Illusion. Im Gegenteil: Machtstrukturen sind schon in der technischen Infrastruktur fest angelegt. Sie führen die Geschichte des Kolonialismus auch in der virtuellen Sphäre fort: in Gestalt des „digitalen“ oder „elektronischen Kolonialismus“.
A few weeks ago, we implemented some important updates and / or changes. For security reasons, we waited a little before making that public.
