The Domain Name System (DNS) is a critical part of the Internet. DNS translates names to IP addresses, a process required for majority of Internet functions. To guarantee the availability and security of Internet services, this tutorial explores DNS concepts and security mechanisms, particularly DNS Security Extensions (DNSSEC).

This tutorial examines in detail the mechanisms to authenticate the communication between DNS Servers, establish the authenticity and integrity of DNS data, and delegate trust.
