Read Hostname and Return IP Address
Dear Experts,
I have a text file on my itanium box which contains list of nearly 1000 hostnames. I do not have the IP Address of them. I want read each entry from the text file and want to do a nslookup to the DNS Server and get the IP Adresses and put them in another file in the format hostname IP Address.
Lets say,
I have abcd.server.com in my text file first line. I want a script which reads this entry and gets the IP Address from DNS and paste in another file as
abcd.server.com 1.1.1.1
the script should then read the next entry in the text file and go until the end of the file and exit.
Thanks in Advance

Use SNAP encapsulation only.
Transmits count requests and waits for each one to time out before
giving up.
interface_name Identifies the interface to request information about.
If a response is received, it prints the IP address to its standard output. This information can be used to configure the interface as
seen in
If a response is not received, the client will retransmit after 2 seconds, and then after 4 seconds. After that, retransmissions occur
every 8 seconds.
RETURN VALUE
Exit status is 1 if the command fails or no RARP response is received. Exit status is 0 and the IP address is printed to standard output
if a response is received.
