What is DNS?

DNS stands for Domain Name System. DNS is an Internet component that translates or converts human-memorable domain names such as solelyweb.com into Internet Protocol (IP) addresses for computers to understand which in turn allows website contents to be displayed.

How DNS Works

  • If you want to visit Google.com you will open a web browser and type google.com into the address bar.
  • Your computer then uses DNS to pull up the nameservers for google.com. Their nameservers are set to ns1.google.com and ns2.google.com.
  • Your computer will then ask googles nameservers for the A record Address for google.com.
  • The nameservers will then reply back with the IP address that is set as the A record 173.194.112.18.
  • Your computer will send a request to that IP address along with the page you are requesting. The server that is hosting google.com will then send your web browser the requested page.
