I don't think I was clear. I have a /19 worth of sprint space which 
wasn't renumbered when I renumbered into my first /18 from ARIN. Since 
then, I've grown to a total of a /16 worth of space, but those 2 /20's 
aren't going away until they decide they no longer went the IPv4 addresses.

Don't get me wrong. I probably should have renumbered them. The cost 
benefit wasn't worth it, though. It still isn't. Forcing a renumber on 
those blocks would cost me much more revenue (if they are going to 
renumber, the business customer might just go to the competitor while 
they are at it) than paying for a sprint circuit.
