nslookup is a utility to query DNS name servers

nslookup is a utility to query DNS name servers. It has two modes: interactive and non-interactive. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Non-interactive mode is used to print just the name and requested information for a host or domain. It is available on several systems like Unix-like systems and Windows systems.
