Before diving into the safety aspect, let’s quickly recap what DNS is and why it matters. DNS is like the phonebook of the internet, translating human-readable domain names (e.g., into machine-readable IP addresses (e., It plays a crucial role in connecting your device to websites and online services.

Why Change DNS Servers

There can be several reasons why you might consider changing your default DNS server:

  • Better Performance: Some alternative DNS servers promise faster response times, which can result in quicker website loading.
  • Improved Security: Certain DNS servers offer additional security features like malware blocking and phishing protection.
  • Bypassing Restrictions: In some cases, changing your DNS server can help you access blocked content or bypass censorship imposed by your internet service provider or government.

The Safety Considerations

While changing your DNS server can offer benefits, it’s essential to be aware of potential risks:

  • Data Privacy: When you use a different DNS server, your internet traffic passes through their system. This means they have access to information about which websites you visit.

    It’s crucial to choose a trustworthy provider that respects user privacy.

  • Downtime: In rare cases, a DNS server might experience outages or perform poorly, leading to slower website loading or even complete unavailability of certain websites. Ensure that your chosen DNS server has a good track record of reliability.
  • Configuration Errors: Incorrectly configuring your DNS settings can cause connectivity issues and prevent you from accessing the internet altogether. It’s important to follow the correct steps and double-check your settings.

How to Change DNS Servers Safely

To ensure a safe transition when changing DNS servers, follow these steps:

  1. Research Providers: Look for reputable DNS providers that prioritize privacy and have reliable infrastructure.
  2. Backup Current Settings: Take note of your current DNS server settings in case you need to revert them later.
  3. Configure New DNS Server: Access your device’s network settings and enter the IP addresses of the new DNS servers you wish to use.
  4. Test Connectivity: After making the changes, test your internet connection to ensure everything is working correctly.
  5. Maintain Updates and Security: Regularly update your device’s software and keep an eye out for any security patches related to the DNS system.

In Conclusion

In summary, changing your DNS server can offer performance improvements, enhanced security, and bypassing restrictions. However, it’s crucial to consider potential risks such as data privacy concerns, downtime, and configuration errors. By researching reputable providers and following proper configuration steps, you can safely enjoy the benefits of alternative DNS servers.
