DNS: Domain Name Server

DNS: Domain Name Server

1. A DNS is an internet protocol which turns human comprehensible websites into machine readable addresses.

   • For example, www.bbc.co.uk will be converted into an address that can be read by the machine.
     • The 'addresses' are known as IP Addresses
       • IP addresses allows the user's computer to connect to the destination web server - to get to what they are after.

2. A DNS server is a database that contains public IP addresses and their hostnames.

   • In more easy to understand terms: a DNS server on the internet is the device that translates that www.lifewire.com you type in your browser to the 151.101.129.121 IP address that it really is.
   • The DNS server is that translator between the hostname and IP address
   • Computers use IP addresses to access websites
