Without the DNS, your browser wouldn't even know which website you're trying to visit
The Domain Name System is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities
A RECORD
The A in A record stands for Address. ... A Records are the simplest type of DNS records, and one of the primary records used in DNS servers. You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks.
CNAME RECORD
A Canonical Name record (abbreviated as CNAME record) is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name)
MX RECORD
The MX records tell which mail server will receive the incoming emails for that specific domain and where your domain's emails should be routed as per the Simple Mail Transfer Protocol (SMTP). The email servers check the MX record of your domain before sending the email.
TEXT RECORD
A TXT record (short for text record) is a type of resource record in the Domain name system (DNS) used to provide the ability to associate arbitrary text with a host or other name, such as human readable information about a server, network, data center, or other accounting information.
