DNS or Domain Name System plays a critical role in how the internet works. DNS is the address book of the internet translating human-friendly names aka domains such as google.com into numeric IP addresses that computers understand. This is achieved via a DNS server identified by a unique public IP address that your computer queries whenever you attempt to connect to any website. In most cases, your internet provider already has a DNS server waiting to make the translations whenever you type in a domain in your computer’s browser and they mostly work just fine. However, your Internet Providers DNS server might go offline or might become too slow perhaps because it’s busy responding to many queries from other internet users. Loading Facebook.com at this point might become slow or not work at all. This is why you would want to consider other DNS servers.
