Multiple C-Block Hosting for SEO purposes
My company is seeking to host 10-20 unique websites, but we need each one to be on a separate class-C IP address. Any ideas on where to start or if this is offered? My searches at GG & Y! have turned up nothing.
The reason I need this is that Google (and probably other SEs) filter links based on the C-block the IP adress for the site is coming from. This is intended to discourage site owners from setting up 50 web sites on the same host, linking them all to one site and artificially boosting the popularity of the site.
I'm not looking to spam Google, but I do need to ensure that my sites are NOT going to be affected by this type of penalty. Thanks for your help.

So are you looking at 10-20 C classes?

There is no evidence that they do and my sites prove same C class IP's dont matter.
The best evidence I have seen is real estate sites all on advancedaccess.com using the exact IP and linking togther yet the do very well for area real estate searches in different areas...
Im wonder where this same C block idea started and who has proof of a filter....
Google themselves state they do not rank based on IP as it would be impossible.

If you have read the hilltop papers and algorithm theories, it's common knowledge that Google does this. The question is only which other engines currently use these results.
I'm not really asking "if" this is a factor, I'm just wondering if there are dedicated hosts that support this
Several Links on Hilltop:
cs.toronto.edu/%7Egeorgem/hilltop/
seorank.com/analysis-of-hilltop-algorithm.htm
forums.seochat.com/t7549/s.html
More evidence on IP C Blocks being a factor in algos:
seroundtable.com/archives/000708.html
forums.seochat.com/t8240/s.html
This isn't a big factor, but every little bit helps.
UltraUnix - Yes, about 20 unique C-Block Addresses would do the job, with room to expand if we were to add more sites.
Thanks for your input to a first-time poster!

I doubt you'll find a host specialising in this kind of requests. I would consider using a few hosts in order to get the kind of thing that you need, even though that would imply some disadvantages (higher costs, managing the websites would be harder to do)

Would co-location be an option? Or would I need multiple machines?

One machine can have multiple IPs.

Sorry to get off-topic from the request made in the original post, but it seemed like some clarification would be helpful for others reading here.Specializing in SEO and PPC management.

20 multiple C class IPs = hard.

Jay - Good point.
My approach has always been "best" practices - which means optimizing and allowing for every little thing I possibly can. There are certainly thousands of sites who aren't affected at all by this and need not worry, but as a professional SEO, whose job requires maximizing every possible gain, it's important that I play not only to whatI think SEs are currently using, but also anticipate the future.
The extent of Interlinked C-Block domains is exceptionally hard to measure in Google's results, but the mere fact that it 'can' be used to devalue link popularity is enough to make me consider looking for a host who could support this request.

Nope. 20 multiple C class IPs = multiple servers.

Looks like you need lots of small webhosting accounts from different providers. From a network standpoint, I'd find it difficult to believe any provider would give you IP's from more then 2-3 /24's, much less 20. Let us know if you find anyone .

There are a lot of people on this forum that have reseller accounts covering a huge range of hosts and IPs. You could offer links in trade for small accounts to be used for your purposes. Maybe in return for onel account, the person gets a link on all 20 sites.
