Certainly not...but as IPv4 is about 4 billion addresses, minus parts that 
can't be used, and not all of it is allocated, and not all that's 
allocated is in use, 1 billion may be more like half the currently used 
space.  That's a lot of IPs, but legitimate mail servers probably are a 
tiny fraction of the "in use" IPv4 space.

This has gone way off-topic for the rbldnsd list, but I think you do have 
some of us interested in exactly what your list does / what its listing 
criteria are?
