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 :-)
