I'm not sure I agree with that. There is a fair bit that goes into the RIB entry - what routing protocol uses it, current state, and so on. I would expect the actual prefix/address to be a relatively small part of that, perhaps 10-15%.

In the FIB, you're approximately correct. The FIB contains the prefix (address and length) and a pointer to a list of zero or more next hops.
