DNS interrogation involves querying the Domain Name System to gather information about domain names, IP addresses, and the structure of a network. This technique is often used in cybersecurity to identify potential vulnerabilities or in network diagnostics to troubleshoot connectivity issues.

DNS Interrogation

The Domain Name System (DNS) acts as the phonebook of the internet, translating human-friendly domain names into IP addresses that computers use to identify each other on the network. It is a hierarchical and decentralized naming system that ensures efficient and reliable access to websites and online services.

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks that aim to access, change, or destroy sensitive information, extort money, or disrupt normal business processes. It requires a multi-layered approach involving technology, processes, and people to effectively defend against evolving threats and vulnerabilities.
