Practical Cyber Hacking Skills for Beginners - Working with DNS Commands

The video tutorial explains the concept of DNS cache and its role in speeding up website access by storing DNS records locally. It covers the Time to Live (TTL) parameter, which determines how long a DNS record is stored. The tutorial demonstrates how to flush the DNS cache using commands and explains the significance of the hosts file in mapping IP addresses to domain names. Practical uses of the hosts file, such as during website migration, are discussed. The video also provides instructions for accessing the hosts file and running DNS commands on Mac systems.
