If this is a local DNS which you have permissions to look at it, you can use nslookup in interactive mode to view the DNS records. See "man nslookup" and review the "ls" command. The "ls -t PTR domain_name" seems to be relevant when compared with just "ls domain_name". There is much variation in the syntax an behaviour of "nslookup" and there is no substitute for reading the manual and trying out read-only commands. The command "nslookup" is being phased out in favour of "dig" but many mainstream Operating Systems still have "nslookup".

I have not been successful in scripting this type of nslookup for multiple enquiries because of the unusual way nslookup drives the terminal but for a single enquiry standard output redirect "> filename" works from the command line in my version.

In any enquiries about machine-specific elements such as comms or hardware it always helps to state the precise Operating System and version.

rpc.nisd_resolv

rpc.nisd_resolv(1M)					  System Administration Commands				       rpc.nisd_resolv(1M)

NAME

       rpc.nisd_resolv, nisd_resolv - NIS+ service daemon

SYNOPSIS

       rpc.nisd_resolv [-v | -V]  [ -F [-C fd]] [-t xx] [-p yy]

DESCRIPTION

       rpc.nisd_resolv	is  an auxiliary process which provides DNS forwarding service for NIS hosts requests to both ypserv and rpc.nisd that are
       running in the NIS compatibility mode. It is generally started by invoking  rpc.nisd(1M) with the -B  option  or  ypserv(1M)  with  the	-d
       option. Although it is not recommended, rpc.nisd_resolv can also be started independently with the following options.

       This  command requires that the /etc/resolv.conf file be setup for communication with a DNS nameserver. The nslookup utility can be used to
       verify communication with a DNS nameserver.  See resolv.conf(4) and nslookup(1M).

OPTIONS

       -F	Run in foreground.

       -C fd	Use  fd for service xprt (from nisd).

       -v	Verbose. Send output to the syslog daemon.

       -V	Verbose. Send output to stdout.

       -t xx	Use transport  xx.

       -p yy	Use transient program#	yy.

NOTES

       available in the Solaris 9 operating environment. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
