nslookup is a command-line tool used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping information. It’s commonly used for troubleshooting DNS-related issues.
Non-interactive mode:
Specify an option inline with the nslookup command. Typically, only one option is permitted on the command line. Run multiple commands to specify different options.
Examples:
> nslookup domain.com type=MX
> nslookup domain.com 1.1.1.1Interactive mode:
Specify multiple options after which you can run queries against a domain that will use the options.
Example:
> nslookup
> set type=A
> domain.com
> set type=MX
> example.com
