Is It Safe to Change DNS?
The DNS addresses in the list we have presented to you are the ones that are very secure. However, changing DNS is not a completely secure process. Unsafe DNS addresses you find on the Internet serve malicious people by redirecting you to different IP addresses.
For example, you might be logging into a similar-looking fake site while you think you’re connecting to Google. While browsing these fake sites, you can get your personal information stolen by being exposed to a trojan attack. Today, when we consider the personal information (our social media user account information, bank passwords, etc.) on our computers, we only trusted DNS addresses or how important it is to use standardized DNS servers.
