Hostname lookup and create text file
I have a list of hostnames in a txt file . I need to do nslookup or other command on linux and get the ip address and if you dont find an ip address then put 0.0.0.0 instead in the output text file along with the hostname.

So input
Code:
host1
host2
host2.dd.ddd.net

Output
Code:
host1, 10.136.21.2
host2,10.127.1.2
host2.dd.ddd.net,0.0.0.0

thanks
G

nsquery

nsquery(1)						      General Commands Manual							nsquery(1)

Name
       nsquery - name server query command

Syntax
       /usr/ucb/nsquery [ lookup ] [ host ] [ server ]

Description
       The command provides an interface to obtain host name and address information.

       If  you	specify  host,	the command obtains information about the specified host. If no host is specified, the command obtains information
       about the local host system.

       If you specify server, the command queries the BIND server that you specify. If you do not  specify  a  server,	the  command  queries  the
       default BIND server.

Options
       lookup  Retrieves the host name, Internet Protocol (IP) address, and aliases of the specified host.  If no host or server is specified, the
	       command obtains information about the local system from the default BIND server.

	       If you do specify the lookup option, the command obtains the information about  the  BIND  server  and  host  specified	(or  their
	       defaults).   If the system from which you issue the command is a BIND server, and you do not specify the lookup option, information
	       about only that server is retrieved.

Files
       Directory containing BIND server data file

       BIND server boot file

       Host database file containing name to address mapping for BIND primary
