There is also Bill Manning's list 
(http://www.ietf.org/internet-drafts/draft-manning-dsua-08.txt).

For those of you at the last RIPE meeting, recall that in the Routing 
Working Group I presented Geoff Huston's proposal that the registries make 
available a list of their unallocated addresses within their /8 blocks.

And I believe all three intend to do that rsn.

For anyone who is a masochist, I've put together a complete list of all the 
addresses which are marked in the three registry databases as being 
unallocated. I use this list for the Routing Report which I post to various 
lists once a week - and it's the basis for figuring out how much IPv4 
address space is left (45.9%).

The list is sitting on a router in my lab at the moment - comes to about 
1500 entries once they are completely aggregated. Once the registries 
produce the lists for their blocks, I'll see how easy it would be to merge 
the two...

I could make this publicly available if folks are interested... It would be 
a BGP feed - exercise left to the reader to figure out how to convert this 
into a dynamically updated routing and packet filter... ;-) Bigger question 
would be whether anyone would even want to do it...
