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 also is 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.
