Moving servers

[SE_Magnets]

We will be moving out servers to a new data center soon, and we are currently using over 100 different ip's. When we move them, would it be necessary to have the ip addresses in different ranges, or can they all be consecutive? Would there abe anything that we should be concerned about?

I assume that if you are moving data centers you will have to get all new ip's. What are you concerned about? Is this related to SEO? The best way to do this is to have the ip's up at the same time. Go ahead and set you DNS TTL to about 3 minutes. This way when you transfer your DNS you don't have much down time. You don't have to worry about IP's being on different subnets unless you are running a bunch of sites that link to each other and are spammy.

Yes we are getting new ip's. I was worried about any negative seo effects. Of course we would cross link all of these site. That would be very bad. Our clients would be PO'd.
