No, my point is that it is already completely trivial, and getting a list from google wouldn't even be worth doing if they did provide it, as you can easily and quickly generate a more extensive list with a single command.
What if I'm a link spammer, then I'd love to have google's list. How can the list be more extensive than google? That is verifiably false. For example, generate a list of IP addresses(500,000+) that have the following characteristics:
1. Have websites that been indexed by google with a PR 2+.
2. Run Web Servers
3. Bonus Points if you can tell me which web servers run the most PR 2+ sites.
Now hopefully you can see how useful this list would be! I don't think nmap will do that for you.
> You are very confused. Asking google for a list of IPs does not provide you with their page rank. IPs are not domains, nor are they websites
No, you are again correct. But if I know the IP address and the domains associated with it's very easy to determine PR 2+ websites and also from there figure out which ones have multiple websites hosted on them.
My point is that this is more efficient, not that it is some super secret 1337 way to hack.
