    'nslookup' is a command-line tool used for querying the Domain Name System (DNS) to obtain information about domain names and IP addresses. It is a widely used tool for troubleshooting DNS-related issues and verifying DNS records.'nslookup' is available on most operating systems, including Windows, macOS, and Linux.

    There are two modes of using 'nslookup':

    Interactive mode: 'nslookup' is launched without arguments in this mode. After launch, a prompt is displayed where users can enter commands and queries. Users can enter queries for specific DNS records, specify a name server to query, or set options to modify the behavior of 'nslookup'. Users can easily query DNS records and troubleshoot DNS issues in interactive mode.

    Non-interactive mode: This mode launches the 'nslookup' tool by passing arguments directly to the command line. The arguments include the hostname or IP address to query as well as any options you want to change. In non-interactive mode, DNS information can be quickly retrieved without the need for an interactive session.

    In both interactive and non-interactive modes, 'nslookup' provides users with a variety of options for customizing their queries. Among these options are the type of DNS record to query (e.g., A, MX, CNAME), the name server to query, and the timeout and retry options.

    Overall, 'nslookup' is a powerful tool for querying DNS information and troubleshooting DNS-related issues. Its two modes of operation provide flexibility for users to quickly retrieve the information they need in a variety of scenarios.
