List of DNS record types

List of DNS record types

A  -Address record  
Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host,

MX - Mail exchange record Maps a domain name to a list of message transfer agents for that domain

PTR -  Pointer record-
Pointer to a canonical name. Unlike a CNAME, DNS processing stops and just the name is returned. The most common use is for implementing reverse DNS lookups, but other uses include such things as DNS-SD.

SOA - Start of [a zone of] authority record -
Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone.
SRV - Service locator
Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX.
