All three. If you look at http://www.iana.org/assignments/ipv4- 
address-space you should find that 59 /8s (989.86 million addresses)  
are currently "reserved" but not for any particular reason so they're  
available to be used.

119 /8s (1996.49 million addresses) are delegated to the RIRs, of  
which 1633.44 million addresses are further delegated as per the info  
on the RIR FTP servers, so that leaves another 363.05 million RIR  
stash addresses unused, for a total of 1352.91 million. (Yes, another  
0.56 million addresses used up since yesterday!)

Currently we're using around 170 million addresses per year, so that  
would give us another 1.5 years. Note though that some IP  
implementations, most notably Windows, don't accept class E addresses  
so it will take a significant amount of time before those would be  
usable.
