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.
