Class C IP's - What are all the things i should look into? Please share your Brain :)

I'm working on a network of almost 20 sites at the moment.
Have 5 Class C IP accounts ( different companies ).

The problem is some companies offer them in blocks like

1.1.1.2
1.1.2.2
1.1.3.2

like that, which means it's quite easy to get trapped by G? ( The class C comes in order like 1 2 3.....).
Also, what about Unique Nameservers for the IP's? Most don't do that.

What precautions & set-ups must be altered here?

Good recommendations on Class C hosting?

Thanks & please share your brain

I use this company, I ordered 10 ips and they where diverse enough. http://www.cclassiphosting.com/

I use them already. More suggestions? Also what about their uptime? I heard dome issues abt their downtime.

I've never had a problem with downtime on C Class IP Hosting ... been great for me!

bump. Thoughts please.....
