DNS query command NSLookup

Description:

The NSLookup command is a program that queries the Internet Domain Name Service. The NSLookup command has two modes: Interactive and non-interactive.

Interactive Mode allows users to query different types of hosts and domain names or output host lists in one domain name to query domain name-related information.

Non-interactive mode is only used to output the information required by the name and host or domain name.
