I'll take it one step further, though: I have yet to see concrete evidence that Google does anything beyond simply logging the IPs and Class C's, at least for SERP purposes. Having worked there, I have a lot of people I'm still in touch with. Unfortunately, it's all cloak and dagger as fuck, but when I was considering SEO hosting, they were like "uh, no."  |
That being said, even if they don't regularly log more than IPs and C classes, it doesn't mean they won't look at them, when they suspect foul play. Case in point, lots of blog networks got penalized and de-indexed earlier this year, along with many of the sites linked to from them. Turns out pretty much all of them were hosting all their sites on one server.
Granted most people's private blog networks won't draw nearly enough attention to themselves as the commercial ones (made solely for selling links and blogposts), you still run an unnecessary risk of getting nailed, if you host everything on the same server.
