Just a neat little trick I have just worked out! If you want to start your own blog network but don't want to pay the huge hosting bill for loads of different class-C ips, then there is a very easy way to host your blogs on different IPs for free (or very cheap). You will need to grab yourself some shared hosting that supports CloudFlare. Loads of hosts now offer this: http://www.cloudflare.com/hosting-partners Choose one, that allows multiple domains on the same account. Set all your websites up on this shared account. Then register an account at CloudFlare, and add all your websites to CloudFlare. CloudFlare in effect acts as a proxy for your websites, and displays your websites from their servers not yours! Each time you add a new website to CloudFlare, they assign it a new IP from their pool. They have a huge pool of IPs, in different class-c and class-b ranges. Therefore all your blogs hosted at CloudFlare are going to have a huge IP diversity. The best thing about this method, other than it being free, is that google won't suspect a thing about your blog network, as there are 1000s of other legitimate websites hosted on the same IPs. This looks natural to google, unlike having your blog network hosted at a specialist class-c hosting provider who is already on google's radar for hosting spammy blog networks.
