Google's scraper bot at least used to be behind IPs that you could identify via reverse-then-forward DNS. Not sure if that is still up to date, though.

Yep, verifying the IPs is still the way to go. You often see websites that do it wrong when you set your user agent to Google Bot and they give you a different version of the page without validating that.
