Traffic Filtering

An overview of Domain Name System (DNS) and the benefits of DNS traffic filtering, including features of Safe Surfing by

What is Domain Name System?

Domain Name System, or DNS is the internet's address book, translating user-friendly domain names like into the numeric IP addresses computers use to identify websites. It acts as a crucial system that enables seamless communication between devices, allowing users to access websites with human-readable names rather than remembering complex numerical addresses. Essentially, DNS facilitates the user-friendly navigation of the internet by handling the translation of domain names to IP addresses.

What is DNS filtering and why is it important?

Using DNS (Domain Name System) traffic filtering offers several benefits that contribute to a safer and more secure online experience. Here are some reasons why you might consider using DNS traffic filtering:

  1. Malware protection:

    • DNS filtering can block access to websites known for hosting malware or distributing malicious content. By preventing your device from connecting to these harmful sites, you reduce the risk of malware infections.
  2. Phishing prevention:

    • DNS filtering helps in identifying and blocking phishing websites that attempt to trick users into providing sensitive information, such as login credentials or financial details. This enhances your protection against online scams.
  3. Content filtering:

    • DNS filtering can be used to block access to inappropriate or objectionable content. This is especially valuable for parents or individuals looking to create a family-friendly or work-appropriate internet environment.
  4. Advertisement blocking:

    • Some DNS filtering services include ad-blocking features, helping to reduce the number of intrusive ads and potentially blocking malicious advertisements that may carry malware.
  5. Improved network performance:

    • By blocking access to known malicious or unnecessary websites, DNS filtering can contribute to improved network performance. It helps in reducing the load on your network by preventing connections to unwanted or resource-intensive sites.
  6. Parental controls:

    • For parents, DNS filtering is an effective tool for implementing parental controls. It allows you to restrict access to specific categories of websites or individual sites, ensuring a safer online experience for children.
  7. Privacy enhancement:

    • Some DNS filtering services offer features like DNS over HTTPS (DoH) or DNS over TLS (DoT), which encrypt your DNS queries. This enhances your privacy by preventing third parties from monitoring your online activities based on DNS requests.
  8. Customization and control:

    • DNS filtering services often allow you to customize and control the filtering rules based on your preferences. This flexibility ensures that you can tailor the filtering to meet your specific needs.

While DNS traffic filtering provides valuable benefits, it's essential to choose reputable DNS filtering services or tools to ensure effectiveness and reliability. Additionally, users should be aware that no security measure is foolproof, and combining DNS filtering with other security practices enhances overall online safety.

Safe Surfing by

Safe Surfing is a privacy and security feature provided by that enhances the way their device connects to the internet.

Safe Surfing main advantages and features:

  1. DNS blocking enabled by default:

    • All benefits described in "What is DNS filtering and why is it important?" are included in Safe Surfing. It means protection against multiple threats, such as malware, phishing, and other potentially harmful websites.
  2. DNS requests through VPN tunnel:

    • As the VPN connection is established to our servers, all DNS queries made by the user's device are now routed through the encrypted VPN tunnel. Instead of using the default DNS servers provided by the Internet Service Provider (ISP), the device uses the DNS servers associated with the VPN service.
  3. Privacy and encryption:

    • Safe Surfing ensures that DNS requests are encrypted, adding an extra layer of privacy. This prevents third parties, such as ISPs or potential eavesdroppers on public networks, from intercepting or tampering with DNS queries.
  4. Security on public Wi-Fi:

    • Safe Surfing is particularly beneficial when using public Wi-Fi networks. The encrypted tunnel protects the user's data, including DNS requests, from potential security risks on unsecured networks.
