Many websites, 4 IPs...SEO?

Hey


I have like 20 domains on 4 ips. I have 7 domains just for having blogs on it. I post to this blogs articles for that pages i do SEO. But..the pages iam doing seo for it are hosted on the same ips.

Will this have any influence on SEO and Google rankings?

As long as you're not doing some crazy closed linkwheel, i believe you should be fine.
