Test your DNS server’s speed/response time

A DNS server (Domain Name Server) will translate a fully qualified domain name (FQDN) to an IP address. In short, if you go to google.com, this request will first be sent to a DNS server. This DNS server will check the IP address which corresponds with this FQDN and will sent back a reply: the IP address of the server which hosts this website.

It is important to have a fast and reliable DNS servers set up for your device as you will probably visit hundreds of websites on a daily basis or even more. So each time you visit a website, your browser or the application you use will have to lookup a domain name’s IP address. So you want this process to be quick and without any errors.
