There servers are more then likely located at rackshack, and I believe they have some with TimPD in the colo4dallas building. More, then likely most host offer a dedicated ip for a extra fee, it is usually considered as a "add-on", with most hosting accounts. What exactly do you need this dedicated ip for?
I hope this helps . Also, from what I hear dot5 is a highly respeceted hosting company. Good luck finding a web host .
- Enter the domain name "dot5hosting.com"
- Click "IP/Domain reverse lookup" to obtain IP
- Select "ain.net" or "arin web interface"
- Click left button which'll say "Lookup IP address"
Neat little things you can do with a couple minutes of time.
