Also, the claim that "IPv6 address scanning is impossible" is generally based on the (incorrect) assumption that host

It also doesn't take into account hinted scanning via routing table lookups, whois lookups, and walking reverse DNS, 
not to mention making use of ND mechanisms once a single box on a given subnet has been successfully botted.

Most software today is very much like an Egyptian pyramid, with millions
of bricks piled on top of each other, with no structural integrity, but
just done by brute force and thousands of slaves.
