I need to know when did Googlebot start using 64.233.167.4 for the first time? I found one date, Feb-4, at http://www.google-dance-tool.com/go...ory.html?g=more

And where can I get up-to-date lists of Googlebot IP addresses? The ones at http://www.iplists.com/ haven't been updated.

My domain was banned. I don't know if it was a manual ban or if it was because I accidentally had duplicate pages in there (long story). How long it would take for googlebot to ban my site after it had detected the duplicate pages? Four days?

If my domain is reinstated will it drop down in the SERPs or do I have a chance to get my previous top positions back?
