Within the penetration testing industry there are multiple companies dedicated to web application hacking. Its popularity has increased as more industries are connecting a range of services to their websites and creating subdomains which can access sensitive information if you can get inside (legitimately or illegally). Multiple resources are dedicated to protect these portals and this is why it is important to understand how both the internet works and how websites/domains work and their relationship to subdomains. Knowing how a domain is laid out is like having a map, instead of stumbling in the dark, hoping you might accidentally come across a vulnerable subdomain you can see exactly where it is and not waste time getting to it.
