What is DNS?
The DNS (Domain Name Servers) is used to maintain a relationship between IP addresses and domain names. DNS is a set of database servers which is used to maintain the relationship between IP addresses and domain names and help in the lookup between the two. Computers use the DNS system to electronically transmit data with other computers through the internet.
