Can you say relative to what the consistency is proved or claimed to be proved? E.g.is Con(NF) claimed to be a theorem of ZFC?

My Ph.D. students and i are gradually working our way through it. The view here is that it is all true, but it's going to be months before we're confident that we are on top of it.
