Different types of DNS Records:
A (address): Maps Host name to IP address. When a computer has multiple adapters cards or IP address it should have multiple address records.
CNAME (Canonical Name): Sets an alias for a Host name. For Example, using this record abc.xyz.com we can have an alias as www.abc.com.
MX (Mail Exchange): Specifies a Mail Exchange Server for the Domain, which allows mail to be delivered to the correct mail servers in the Domain.
NS (Name Server): Specifies Name Server for the Domain, which allows DNS Lookups within various Zones. Each Primary and Secondary name server should be declared through this record.
PTR (Pointer): Creates pointer that maps an Ip address to a host name for reverse lookups.
SOA (Start of Authority): Declares the host that's the most authoritative for the zone and is the best source of DNS information for the zone.
