Forward and Reverse Lookups are fundamental concepts in the Domain Name System (DNS). Forward lookup involves translating a hostname (such as www.example.com) into its corresponding IP address (192.168.0.1). It allows users to access websites and services by using human-readable domain names. Reverse lookup, on the other hand, performs the opposite function.
It takes an IP address and retrieves the associated hostname. This is useful for network troubleshooting, security analysis, and verifying the authenticity of incoming connections. Together, forward and reverse lookup mechanisms facilitate the smooth functioning of DNS, enabling seamless communication between devices on the internet.
