Changing your DNS server to 8.8.8 on Ubuntu can help improve your internet connection speed and security. DNS (Domain Name System) is responsible for translating domain names into IP addresses, allowing your computer to communicate with websites and online services.
What is 8.8?
Before we proceed with the steps, let’s understand what 8.8 actually is. 8.8 is a public DNS server provided by Google, known for its reliability and fast response times.
Why Change Your DNS Server?
There are several reasons why you might want to change your DNS server:
- Faster Internet Speed: By using a faster DNS server like 8.8, you can experience quicker website loading times.
- Bypassing Restrictions: Some ISPs (Internet Service Providers) may block certain websites or impose restrictions on accessing specific content. Changing your DNS server can help bypass these restrictions.
- Better Security: A reliable DNS server like 8.8 can provide enhanced security by blocking access to malicious websites and protecting you from phishing attacks.

Verifying Your DNS Server
