I have 2 VPS’s, both with Future Hosting (very happy with them btw). Their purpose is solely to host my own sites.
Each VPS has 1 shared IP, to which I’ve added a number of additional dedicated IP’s. For my ‘important’ sites, I put them on their own IP, so that when I interlink some of them, the links aren’t all coming from the same IP.
Here’s my question - I assume that these ISP’s dole out their IP’s from their own Class C blocks. Am I still getting the ‘link diversity’ I think I am if all the IP numbers are from the same Class C?
I think that for google your web sites will be different and it will never consider them as the same if there are diffrent design, but links from your web sites will not not be considered as 2 links. I believe that will be considered as one.

If you have a chain of the web sites and then going to sell links from then so those links in bulk from your web sites will be weasting due to the same C class. Al least for Google.
If you need differnt C class hosting you will need to do the search for the SEO hosting.
I have often wondered how ‘far’ Google goes in this regard. Certainly, it wouldn’t be hard to find connections by comparing whois info, onpage contact info, link IP addresses, etc. On the other hand, this would be fairly ‘expensive’ assemble and compare this info as such - grouping sites that are linked, gathering whois info, comparing link IP’s within IP blocks, etc. It would add a significant additional burden to the whole rank evaluation calculation.
I guess the real question is just how far Google goes in this respect.

I think it all rests on how many domains we’re talking about. My personal opinion is that interlinking up to 10 sites isn’t likely to get you into much trouble. Once you get into the hundreds, you’re very likely to trigger some threshold at the likes of Google. Those domains, even if they’re not close neighbors, likely have common IP whois info (not to mention your own domain’s whois info). I’m pretty sure that search engines are not quite so easily fooled, so if you’re trying to do that, you’d better make it look like really natural linking, from totally unrelated websites.
Black hat SEO can be such a nightmare to do “right”.

I don’t think they run this kind of advanced testing on all websites/pages, because it would indeed become prohibitively expensive to run the search engine. My personal opinion is that they have a threshold that triggers further investigation.
Google is pretty careful not to reveal how the algorithm works in precise terms. They’re not going to tell us “we do a detailed check only if 150 domains or more engage in interlinking”.
I do not think this is a problem. From an SEO stand point it may not be all the way correct and you could be flagged by Google but I do not think with the amount of Websites that you have it should be a huge problem.
It depends upon who’s looking at it. SEOs may or may not, outfits like SpamHaus will gather an entire ISP’s block and whack them all for a single spammer in their midst.
IMHO, it will only make a difference if you need secure server certs for those domains.
