You can find a list of space allocated by the RIPE NCC here:

ftp://ftp.ripe.net/ripe/stats/issued/

Also in this directory is a script to invert these, so you can get an
unallocated space.  These files are updated every 15 minutes.

Please see this file for full details:

ftp://ftp.ripe.net/ripe/stats/issued/README

This listing has been published for two weeks now, and was presented
at the Routing Working Group at RIPE 44.  My apologies for not making
this more public, we are going to do this soon.

We are also working with the other RIR's in an effort to produce this
information on a global basis.
