Changing your IPv6 DNS server can help improve your internet speed and security. By default, your device uses the DNS server provided by your internet service provider (ISP). However, you may choose to use a different DNS server that offers better performance or additional features.

Why Change Your IPv6 DNS Server?

Improved Performance: Some DNS servers are optimized to provide faster response times, resulting in quicker website loading and improved overall internet speed.

Better Security: Certain DNS servers offer advanced security features such as blocking malicious websites, protecting against phishing attacks, and filtering out unwanted content.
