NSLOOKUP (short for "Name Server Lookup") is a command-line tool that is used to query the Domain Name System (DNS) to obtain domain name or IP address information.
The
primary use of NSLOOKUP is to troubleshoot DNS-related problems such as
verifying that DNS servers are responding properly, checking for DNS resolution
errors, and identifying DNS misconfigurations. It can also be used to obtain
information about a specific domain or hostname, such as the IP address of a
website, the MX record of a mail server, or the name server(s) responsible for
a domain.
NSLOOKUP
is a powerful tool that provides a way to diagnose and troubleshoot DNS issues.
However, it requires some familiarity with DNS and networking concepts, as well
as knowledge of how to use the command-line interface.
