Hi,
 
I'm looking for a tool that sends a query to the database whether the source ip is in the db or not. The database which will be looked up for the query should contain the ip allocations and ISP ip blocks of the all RIR's (RIPE, ARIN, LACNIC, APNIC, AfriNIC) and it must be keep updated in a period of time, for example, daily. The tool will give permission or restriction to the packets by sending query to the updated database and new allocations will not be discarded. 
 
How could i achieve this ? 
 
Thank you.
