Tier two blogs. Are clustered IPs a danger?

Hi,

All my sites are on one dedicated server (several different ips all close together) and i'm linking them in a pyramid form.
I'm thinking about blasting some 2.0 property links to tier two blogs.

These blogs are only a few ips away from either other and the money site.

Is this is a huge danger?

What would you recommend? Getting some shared hosting accounts?

Update:
After doing some reading on DP. it seems that to host on a single server, multiple C class ips are needed for each site. Please correct me if im wrong.

 

how much would it cost to buy ip blocks spread apart?

 

does it make a difference if all my sites are on one server?

Yea bro, you need to get ip's in all different class c ranges. If your provider won't do it for you just search for "seo hosting" to get started on your hunt.

 

just dont link them together.

should get some differnet class a ip's also


*there are lots of other factors to be considered
