DNS interrogation

As a future cybersecurity professional, understanding the purpose of various applications and network protocols is very important. In this section, we are going to focus on a particular protocol: Domain Name System (DNS).

Let's begin by further understanding the role of DNS and how we can obtain information as a penetration tester.

What is DNS and why do we need it on a network?

DNS is like a telephone directory containing names, addresses, and telephone numbers. DNS is used on networks—both the internal networks of organizations and external networks across the internet. The DNS protocol is used to resolve hostnames (domain names) to IP addresses.

Before DNS, each computer contained a hosts file...
