It seems to me like the best solution might be a semi-hacky solution of asking arin (and other IRR's) if i can copy its DB and creating an internal peer which null routes unallocated blocks (updated nightly?)
Has anyone seen an IRR's DB's not being updated for more than 30 days after allocations? I always assumed that they are quickly updated.
Note, ARIN is an RIR, a regional internet registry, which is what I presume you meant there. Nevertheless, while it might be worth a try from a research perspective, it may be a bit risky in a production environment. In addition, someone may announce a more specific so keep that scenario in mind. The CIDR Report monitors RIR allocation data. This may be of interest to you: <http://www.cidr-report.org/bogons/rir-data.html> You can get access to that allocation data as noted here: <https://www.arin.net/knowledge/statistics/rir.html> John
