What Is Open DNS Server?

An Open DNS server is a public Domain Name System (DNS) resolver that allows users to bypass their internet service provider’s (ISP) default DNS server and use a different DNS provider. It provides an alternative way to resolve domain names into IP addresses and offers additional features such as enhanced security, improved performance, and content filtering.

Why Use Open DNS Server?

There are several reasons why you might consider using an Open DNS server:

  • Enhanced Security: Open DNS servers often come equipped with advanced security features such as phishing protection, malware blocking, and botnet detection. By using an Open DNS server, you can add an extra layer of security to your browsing experience.
  • Improved Performance: Some Open DNS servers are known for their faster response times compared to ISP-provided DNS servers.

    By utilizing these servers, you may experience quicker website loading times and smoother online activities.

  • Content Filtering: Open DNS servers offer content filtering options that allow you to block access to certain websites or types of content. This can be particularly useful for parents who want to create a safer online environment for their children.

How to Set Up Open DNS Server

To start using an Open DNS server, follow these steps:

  1. Determine the IP addresses of the desired Open DNS servers:
  2. You can find a list of publicly available open DNS servers on the internet. The most popular ones include Google Public DNS (8.8.8 and 8.4.4), Cloudflare (1.1.1 and 1.0.1), and OpenDNS (208.67.222.222 and 208.220.220).

  3. Configure your network settings:
  4. In your network settings, locate the DNS server configuration section and enter the IP addresses of the Open DNS servers you want to use.

  5. Save your settings:
  6. After entering the desired Open DNS server IP addresses, save your network settings.

Verifying Open DNS Server Setup

To verify that you have successfully set up an Open DNS server, follow these steps:

  1. Visit a DNS leak test website:
  2. There are several websites available that can test whether your DNS queries are being resolved by the Open DNS servers you specified.

  3. Perform a DNS leak test:
  4. Follow the instructions provided on the website to perform a DNS leak test. The results will indicate which DNS server is being used to resolve your queries.

Note:

Keep in mind that changing your DNS server settings may affect other aspects of your internet connection, such as VPN connections or certain applications that rely on specific DNS configurations.

If you encounter any issues or notice unexpected behavior after configuring an Open DNS server, you can revert back to using your ISP’s default DNS servers or seek assistance from technical support.

In conclusion, an Open DNS server provides an alternative option for resolving domain names into IP addresses while offering enhanced security features, improved performance, and content filtering capabilities. By following the steps outlined above, you can set up and verify the usage of an Open DNS server to enjoy these benefits.
