nslookup
nslookup
The nslookup command queries a DNS nameserver. It can be run
in interactive mode. If no host name is provided, then the program enters
interactive mode. By default, the DNS server specified in
/etc/resolv.conf
is used unless another is specified. If we want to specify a server but not look up a specified host, we must provide a - in place of the host. The syntax is
> nslookup [host|-[server]]
