This isn't exactly what you asked for but it may help - it's a script I
wrote to help me resolve addresses for debugging. All it does it is
call the unix system call 'gethostbyname', but that lets you look in
/etc/hosts, nis, netinfo, etc. whereas dig, nslookup, host are just for
DNS as you found. You can spend too much time on a problem only to
find it's due to an old /etc/hosts entry you didn't notice. DAMHIKT.
Usage: ./gethostbyname.pl hostname.

use Socket;
my $host = shift;
my ($name,$aliases,$addrtype,$length, at addrs) = gethostbyname($host);
print join ( ', ' ,
map(
inet_ntoa($_),
@addrs
)
) . "\n";
--- end gethostbyname.pl ---
