Domain Naming Services or System: It is used for resolving host names to IPs and IPs to Host names.
There are 5 types of DNS records: A, CNAME, NS, MX, and PTR.

A records: Address (A) records direct a hostname to a numerical IP address.

CNAME records: CNAME allows a machine to be known by one or more hostnames.

NS records: NAMESERVER (NS) records specify the authoritative nameservers for the domain.

MX records: Free e-mail services such as everyone.net require that MX changes be made in order for their software to work. This change allows mail destined for your domain to be directed to their server.

PTR records: Pointer records (PTR) are used for reverse lookups.
