A resource record is the basic data component in the Domain Name Service (DNS). DNS resource records define not only names and IP addresses but domains, servers, zone, and services as well. This list shows you the most common types of resource records:

Type Purpose
A Address resource records match an IP address to a host name.
CNAME Canonical name resource records associate a nickname to a host name.
MX Mail exchange resource records identify mail servers for the specified domain.
NS Name server resource records identify servers (other than the SOA server) that contain zone information files.
PTR Pointer resource records match a host name to a given IP address. This is the opposite of an Address record, which matches an IP address to the supplied host name.
SOA Start of authority resource records specify which server contains the zone file for a domain.
SRV Service resource records identify servers that provide special services to the domain.
