Recently I've been wondering if using, or setting up an DNS would "improve the overall system stability and make adjustments to enhance my user experience", I'm just a bit worried about my privacy on the Internet. Aside of using trusted sites, I'm wondering if setting up a "personal" DNS would make my Internet browsing safer. Truth is that... I have never went somewhere else on the internet besides Facebook, Pinterest, DA, Youtube... this place... and some random pages that contains information of my interest. Now I'm interested in registering my credit card on the Internet (Paypal, Amazon, Etsy, etc. etc.) and I'm worried about what could go wrong with that information. Then I found OpenDNS ... but as far as I know about the site, you just settup their DNS address and voilá... more privacy and info-protection. While I do understand what an DNS is, I can't quite grasp why certain DNS are "better" than others and how they can provide information protection. Would my information be safer if I settup an DNS addres? (different from the one I currently have) Does having an Open DNS, a Public DNS or a Private DNS grants me with user info protection?
