Types of DNS Lookups

Types of DNS Lookups
DNS is most commonly used by Web browsers, automatically converting Internet domain names to IP addresses.
Beside these forward lookups, the DNS is also used for:

finding the correct servers to deliver Internet email
reverse lookups that convert an IP address back to a domain name

The network requests supporting DNS lookups run over TCP and UDP, port 53 by default.
