If you're interested to know who else is hosting on your shared IP there are several free services that will do a reverse IP domain check [google.com].
Though Google does note IP address of websites and does give better PR if links are from websites which are further away. Links to websites on the same IP don’t count for much.
Also, Google may have a higher trust factor with certain IP more than others based on websites that exist on them. (its only a guess of mine). Which is why I keep undeveloped websites on a different IP address.
ex: there are A, B, C three sites and A and C site in same ip then a site have inbound link frm b and b also gives backlink for c , here algorithm plays roll, then this linking does matter, doesn’t it.
