Sometime we got following Error "nslookup: command not found"
ERROR :-
[root@amitmaheshwari.in ~]# nslookup
-bash: nslookup: command not found
SOLUTION :-
The nslookup command is a part of the BIND utilities so you need to install them.
To install the BIND utilities, type the following:
[root@amitmaheshwari.in ~]# yum install bind-utils
[root@amitmaheshwari.in ~]# which nslookup
/usr/bin/nslookup
