Common DNS Record Types

A DNS zone stores different kinds of resource records, each mapping a name to a specific piece of information. The record type tells you what kind of answer it provides.

The exam expects you to recognize the most common types and what each does. This lesson covers the essentials.

The A record (Address record) maps a domain name to an IPv4 address. It is the most common record and the one most lookups ultimately seek.

For example, an A record might map example.com to 93.184.216.34. When you browse to a name, an A record usually supplies the IPv4 address you connect to.
