I can't find it now. But there used to be a test php script to run to determine that your existing server is compatible.
But most all at least shared hosting plans work.
As far as static ip you can contact express hosting for the costs I do know they have a limited number of them.
Okay found the test script hiding at"
https://www.ubbcentral.com/demo.phpIt is a form to request a test demo at the vendors site
Look at the bottom of the screen for server test.
