Protect your computer from malicious actors Internet privacy is an important issue in today’s digital world. Protecting your privacy and security online is a way to keep malicious parties away from your computer and devices. Private DNS is the answer.

You may be concerned about your online privacy, and you want to make steps to improve it. Continue reading to find out what private DNS is and how to configure it on your devices.

What is DNS?

The Domain Name System (DNS) maps the web address that you search (like online-tech-tips.com, otherwise called the URL or Unified Resource Locator) to a set of IP addresses so that packets are efficiently sent over the internet.

A DNS server usually performs the translation from URL into IP. This is known as a DNS transaction and it occurs every time you visit a site, use specific applications or communicate with certain platforms.

These transactions, just like domain names, cannot be encrypted. The transactions are not protected by privacy mechanisms. Operators and others can see and log transactions easily, which can lead to serious problems if the information poses a privacy or security risk.

It can also make you vulnerable to malicious cyberattacks, such as man-in-the-middle attacks.

What is Private DNS?

Two new terms are available to help you understand private DNS: Transport Layer Security, (TLS), and Hypertext Transfer Protocol Secure. These protocols protect any DNS queries that are sent, and DNS over them is referred to as DoH and DoT (DNS Over HTTPS and TLS).

DNS security vulnerabilities are a key component of many malware, ransomware, and data theft attacks. Private DNS is the solution. DoT and DoH both encrypt communication between your network, the DNS server, and prevent third parties intercepting it.

You can also use a SmartDNS and a VPN.

What is Private DNS?

This process may vary depending on the platform/device you use. You will need to set up private DNS on your device. Also, you must have access to a third party DNS server with DoT and DoH functionality.

This will confirm that your DNS queries have been encrypted. It will also verify whether your browser supports encrypted Server Name Indications (SNI), if your DNS resolver uses Domain Name System Security Extensions (DNSSEC), as well as which version of TLS you are using.

Internet Privacy

Public DNS is one the most important security concerns. Configuring private DNS can help protect you and your devices against malicious actors.
