fetching multiple fields from database

Hi,

I have a database with IP address and hostname of a server.  Now the
problem 
here is some of the servers are running in cluster and have duplicate 
hostname.  I am looking for a command/suggestion that incase if i type a 
hostname. It automatically shows all the corresponding IP Address of the 
given hostname.

Please help.  Attached below is the sample database.

IP Address                         Hostname
10.1.1.2                             Juni
10.1.6.8                             Ora
10.1.5.6                            Tetli
10.1.1.6                            Juni
