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,
