Google Pagerank and "Class-C Addresses"

I'm looking into a weird request which more and more customers have.
They want "different Class C addresses", by which they mean IPs in
different /24 subnets.
The apparent reason for this is that Google will rank links from
different /24 higher then links from the same /24. So it's a SEO
I googled a bit and found pages after pages of FUD and such great
things as the "Class C Checker": "This free Class C Checker tool
allows you to check if some sites are hosted on the same Class C IP
My question is: Is there any proof that Google does differentiate
between /24s, or even better is there any proof that this isn't the
case? I will not give a customer space from different address blocks
just because he read it in a SEO magazine.
Perhaps someone from Google itself can answer this question?
Also how do you handle such requests? I expect I'm not the only one
who gets them.
