Let's take a step back - what are you trying to do? Map out the network? Just figure out what all the subdomains are? You can probably roughly map the network with public information (whois, plus rDNS queries for every address in the whois info), but getting a list of forward lookups that are subdomains is going to be harder. -- -------------------------------------------------------------------------- | Stephen Gran | Modesty: The gentle art of enhancing | | steve@lobefin.net | your charm by pretending not to be | | http://www.lobefin.net/~steve | aware of it. -- Oliver Herford | -------------------------------------------------------------------------- Attachment:
