You sure don't need Net::DNS for that.
Here is a very simple script that list all ip's associated to a hostname (or
any name known on your DNS).
I use the same script on windows or linux it just work asis :
--------------------------------------------------------------------------------------------------
#!/usr/bin/perl -w
#------------------#-------------------------------------------------------------
# Param 1 = windows name of a machine
# Return = IP or list of IP of that machine
#--------------------------------------------------------------------------------
#
#
use Socket;
my $poste = $ARGV[0];
if (!$poste) {$poste = "localhost";}
# gethostbyname method
my $host = (gethostbyname ($poste))[0];
print "================\n";
printf "Adresse(s) IP de $host\n";
my @addr = gethostbyname ($host);
splice @addr, 0, 4;
print "================\n";
foreach (@addr) {
printf "\t%s\n", &inet_ntoa ($_);
}
---------------------------------------------------------------------------------------------
I wish to give credit to an unknow author on PerlMonks (
http://www.perlmonks.org/ )
from wich I took inspiration and some lines of code few years ago.
Good luck,
BT
