- 2. What is DNS? Domain Name System (DNS) is a protocol under which a domain address is converted into an IP address and redirects the browser to a particular web server where the website files are hosted. This server then returns the requested web page and displays it in your device’s browser. A domain name system can also be termed as Directory of the Internet, where it searches for the IP address associated with the specific domain name. Each device connected to the internet has a unique IP address, using which other machines communicate with it.

- 4. Domain Name System (DNS) Records There are various types of DNS records, which are used to connect a domain to respective web services like a website, email, sub-domain configuration, etc. We will discuss the most commonly used DNS records in this section. A or AAAA record- This type of DNS value associates a domain to the specific IP address of the webserver. A record is used for IPV4 address, whereas AAAA record is used for IPV6 address. In case you want to point the website to a different server and all other web-based services like email to others, you will have to update this record only, which will consist of an IP address. MX Records-It stands for Mail Exchanger record. This is another very useful DNS record used for configuration of domain-specific emails. It is used to assign a web server to send and receive emails for the domain. Setting this MX record to point to a specific server will help you host your emails on a specific server.
