Private networks were working in before google penguin update. I have 20 different domains in private networks with 2-8 PR. I have built them different IP and servers. Some are old and have high authority. I add unique articles and have found a marvelous effect on the search engine. I have seen no problem after search engine updated. Right now working on 50 different domains. So what is our opinion about this?
