I've had good luck with the rank of my web design site in my local market. I link to them from my site, which has proven itself to be of value for them and and I believe their links to me help me with how my site ranks. They've been spread out over several IP addresses just by chance. I was moving everything over to a new reseller account for simplicity, but they have been getting a lot of ddos attacks so I'm shopping again. I've noticed that they had a multitude of different IP addresses my sites were on, and no other reseller hosts I've looked into do. Is this of value? If all my client sites were coming from the same IP, would those incoming links have less value?
