AFAICT, you're going to need some way of determining, based on the information
you get from facts, which server gets which IP address. You could do this with
an external node classifier, or some algorithm (custom functions could help
here).
Don't know if anyone can provide better ideas than that, but hopefully this
gives you somewhere to start.
