What is DNS Filtering?

DNS stands for Domain Name System. It’s often likened to a phonebook of the internet, translating human-friendly domain names (like “example.com”) into machine-readable IP addresses (like 192.0.2.1). DNS filtering, therefore, is the process of using the DNS to block access to specific websites or content by preventing the resolution of their domain names into IP addresses. Essentially, if the website’s domain name is on a block list, the DNS filter will prevent your device from accessing it.

How Does DNS Filtering Work?

DNS filtering operates on a simple yet effective principle. Here’s a step-by-step breakdown:

  1. Request Initiation: When you try to visit a website, your device sends a DNS query to translate the website’s domain name into an IP address.
  2. DNS Server Check: The query reaches a DNS server configured with Domain Name System filtering. This server checks the domain against a list of blocked or allowed sites.
  3. Filtering Decision: If the domain is on the block list, the DNS server returns a “null” response or redirects to a block page, preventing access. If it’s not blocked, the server returns the correct IP address, allowing your device to access the website.
  4. Access Granted or Denied: Depending on the DNS server’s response, you’ll either reach the intended website or receive a message that the site is inaccessible.

Why is DNS Filtering Important?

Cybersecurity Protection: It is a frontline defense against phishing attacks, malware distribution sites, and other cybersecurity threats. By preventing access to known harmful sites, it significantly reduces the risk of cyber attacks.

Content Filtering: For parents and educators, it is a vital tool for controlling access to inappropriate content such as adult material, violent content, and more. It helps in creating a safer online environment for children.
