You can at least get a list of all the allocated blocks. Presumably 
anything not allocated is unallocated and is a candidate for blocking.

for rir in afrinic apnic arin lacnic ripencc; do wget 
ftp://ftp.ripe.net/pub/stats/$rir/delegated-$rir-latest; done

These are updated daily and include both IPv4 and IPv6 allocations.

Now, what I would really like is an arin version of ripe.db.inetnum.gz :-)
