How to set up Private DNS on Android Phone for Security Privacy and Adblock

Private DNS can be a great VPN alternative to get rid of annoying advertisements, online tracking, and to protect your Android phone from malware. Make your web browsing faster, safer, and more comfortable! Currently, almost all public internet connections are unencrypted, which makes them vulnerable to being intercepted by files that attackers have access to network channels, reducing the privacy of users. Recent news reports have elevated these concerns.

Private DNS on Android uses the TLS protocol, such as HTTPS. The encryption provided by Transport Layer Security (TLS) eliminates opportunities for eavesdropping and tampering with DNS queries on the network. DNS over TLS is a way to send DNS queries over an encrypted connection. This new feature simplifies the process of configuring a secure custom DNS resolver on Android, which means the parties between your Android mobile and the websites you visit won't be able to snoop on your DNS queries. TLS covers DNS to control the privacy risks that arise from the ability to eavesdrop on DNS messages such as person-in-the-middle, ISPs, Mobile Operators, and others.

Why use a Private DNS?

Behind the reason, there are benefits of use.

  1. Get a faster internet connection compared to using ISP DNS services.
  2. Avoiding censorship.
  3. Internet as safe as possible against threats and filtering such as ad-blocking, porn-blocking, phishing, malware, harvest data, etc.
  4. Centralized and scheduled reporting.
  5. Redundancy (smart caching).
  6. Access to unofficial alternative top-level domains not found in the official DNS root zone.
  7. Temporary unavailability of the ISP's name server.
