So a bit more than 35% of the space in the registry is without any 
RSA/LRSA?

I am guessing that most of that was in the form of the original class "A" 
networks of various older federal agencies and otherwise who do not really 
have an ARIN budget, but that is just a wild guess.

Is there any breakdown of how MANY total orgs with no RSA, and how many of 
them are class "A" (/8), versus just holding a single /24?
