IPs from different class-C-nets sure SEO strategy?

There is already a similar-titled thread explaining the benefits of that.

But look what I discouvered, the partitioning of a/b/c-class nets is past:
http://en.wikipedia.org/wiki/CIDR

Seemingly, the game is not that easy. What if G discouvers, that all your IPs belong to a 'CIDR'-subnet? Is then there any extra benefit than just taking
aaa.bbb.ccc.1 to 254?

Is it possible to check to which net a host belongs?

I just bought 100 domains and am on the way to order additional IPs. Now I don't know if I should pay the extra money, when the IPs come from different C-classes.

Where are the experts?

Does it make sense what I said? Is there extra benefit, if you have IPs from different class C networks?

Or is it completely sufficient to use an class-C IP range like 123.123.123.100 - 123.123.123.200 ?

Thats D class mate, C class would be the third "123" from the left part of the above IP.

I have recently been using seo-host for setting up my own blog farm, and although its a bit early to see what will happen, I feel pretty confident that it will give me a nice advantage.

I am pretty sure that there is another host, out there that will give you completely unrelated C-Class IPs, and also they will be your own, without having to share.

I saw it somewhere on here the other day, so have a search or two for c class IPs and you might find the one I am thinking of....

Good luck with it!

Usualy a webhosting company (honorable one) has in the offer details about the ips. Next things is tat you can ask the support. Finaly this isn't one of the most important facts in SEO, its true is good to have backlinks from sites that have class C ips, but not by far as important as the sites number of indexed pages, PR and so on!

Modern routing happens usually through cidr and not the old subnetting.

But no one here knows what google really does and what their tools really look for

unless your using the same nameservers on each "site/ip address" it would be difficult for them to block it. They're not going to block an entire C class of ip's, just because one guy has a blackhat blog up

This is not about blocking or delisting.
This is about google using backlinks to increase/define the pagerank of a linked site.

And if your backlinks some from the same class-c the pagerank does not seem to get really influenced by those.
