DNS issues & troubleshooting guides

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. In other words, it is a server that binds the IP address of a website to an easily recognizable name needed for the purpose of locating computer services and devices worldwide.

For instance, if you want to open a particular website, such as Facebook or Google, you’ll type its name in your browser instead of something like 176.13. 69.63.
