What it is: To protect your privacy, Cloudflare offers a new DNS service.
When you type a web address like www.yahoo.com, that information gets sent to a DNS (domain name server), which then attempts to decipher your text and translate that into its numeric equivalent. That’s because all websites are actually defined by numeric designations like 188.8.131.52. To spare people from typing in a list of seemingly meaningless numbers, you an just type in a much easier to remember name and a DNS server figures out how to find that website’s actual IP (Interpret protocol) address.
For most people, their Internet service provider offers a free DNS service, but this also means your Internet service provider can spy on your browsing history. If you don’t like that, use a different DNS server. That’s why a company called Cloudflare offers a free DNS service that doesn’t track your browsing history. By using a different DNS server than the one your Internet service provider offers, you can avoid giving data to your Internet service provider and use a more secure DNS server at the same time so nobody can track your browsing history.
Of course, anyone who has access to your computer will still be able to access your browser’s history so you may want to use the special privacy mode in most browsers to avoid tracking your browsing history as well.
With Facebook revealing they abused users’ privacy and more companies likely doing that everyday, it’s important to minimize access to your data as much as possible. By using Cloudlfare’s free DNS service, you can at least keep your browsing data safe from your Internet provider.
