national allocations

Dear all, i'd like to know - does anybody use allocations list submitted by RIPE NCC in order to automatically extract info about national allocations ? For instance, when we need to define whether current IP-address belongs to RU provider we ask whois <IP-address> | grep "country: *RU" (i guess country field with correct country code presents in all of inetnums) however sometimes it's necessary to know all of IP-addresses that were allocated to national providers, so we've to get allocation file, find only RU entries and furher update our local database. Is there are any ways to know that RU LIR has been added to file ? With respect, --- RIPN Registry center -----
