WHAT ARE DNS RECORDS ?

A DNS record is simply a database that maps human-friendly URLs to IP addresses. When someone types in a URL such as google.com, that entry is sent to an internet service provider (ISP) where it’is forwarded to the DNS servers, and then directed to the proper web server using the corresponding IP address as a label.


TYPES OF DNS RECORDS:-

1.A Records.

2.AAAA Records.

3.CNAME.

4.MX Record.

5.TXT Record.

6.NS Record.

9.SRV Record.

10.SOA Record.
