What is DNS - Domain Name System ? DNS is a protocol within the set of standards for how computers exchange data on the Internet and on many private networks, known as the TCP/IP protocol suite. Its basic job is to turn a user-friendly domain name like google into an Internet Protocol (IP) address like 74.125.135.104 that computers use to identify each other on the network. Its like your computers GPS for the Internet. Computers and other network devices on the Internet use an IP address to route your request to the site youre trying to reach. This is similar to dialing a phone number to connect to the person youre trying to call. Thanks to DNS, though, you dont have to keep your own address book of IP addresses. Instead, you just connect through a domain name server, also called a DNS server or name server, which manages a massive database that maps domain names to IP addresses.
