In a new linux server, when you try to run the command given below, it will be getting error.
[root@server /]# host abhionlinux.in
-bash: host: command not found
In such cases, you need to install the bind-utils package in the server.
1. ssh to the server.
2 run the command
[root@server /]# yum install bind-utils
Now host, dig and nslookup will be working fine.
