None of this is really magic, and is publicly
available via a variety of sources...


I would like to know what techniques can Intruders
use to obtain a lists 
of hostname and attack them with exploits code?
For example, a huge list like:
www.foo.com
www.bar.com


Scanning, mostly.  Also, DNS zone transfers, but many
times it's just plugging a class C or B address range
into a scanner and hitting enter.


And so on. Also, they can have a lists with certain
criteria in common 
(os, httpdver) and do a more selective attack. I
want to know how they 
can obtain hostnames asnd create a huge database for
potencial host victims?


Besides the usual scanning techniques, throw Googling
and searches via Netcraft for httpd's into the mix.
