Question on load-balancing, different IP's, server clusteri and Google

.. does it negatively influence our results? (a bit technical)

[Bamikanarie]

Im doing some research on the current state of SEO and the whole optimizing thing, and I keep on encountering posts on the different domains, same IP issue (like shared/virtual hosting). And i have an even more complicated question:

Our company has a lot of different domains: our company's main site, and all kinds of different domains/sites for products and brands. We host them ourselves, on a load-balanced server-cluster. We use round-robin load balancing: which means our nameserver returns the IP's for a domain in a random order (with short life-span), so mathematically the requests are distributed evenly among the different machines (which each has it's own IP).

But does this negativly influence our search results? I should think not, because it's the same domain, same content, but server from different IP's. And besides, it's the domain name that gets listed in Google right?

Can anyone shed some light on this? Am i being paranoid?

Due to the severity of this issue i'm doing a very shameless bump. (i think i can because this issue may well apply to a lot of websites).

I use round-robin load balancing, with the underlying servers on different continents, and see no harmful effects.

A little more information would help..

Are the IPs all in the same class/registered to the same owner in ARIN/RIPE?

The content is exactly the same regardless of which box serves it, right?

Just from looking anecdotally across the web at major websites (Yahoo, CNN, msnbc etc) I don't think it's a big deal.
