1.) i asked the same question in the "Proxies, Anonymity" section but does anyone know a tool which will leech the ip-addresses or the host names into a file without the other crap like banners or other text?

2.) Is there a tool out there which will look up the addresses to see whether they are still active or not? i mean a kind of ip-scanner ...

3.) If you want to write fake-mail i suggest using "Aenima - The Ressurection" ... Actually, it's an email-bomber but it offers many more options and you can use it to write emails with arbitrary email-addresses as despatcher. if there's a tool out there which will weed out the bad hosts you can import the list from www.senfakemail.com directly into Aenima
