Use of the RIPE database

Are these groups uptodate?
Do we care?
Disregarding internal networks and private peering, routing information on the Internet is essentially public (traceroute, looking glass...). It must be public because otherwise networks would not be reachable, meaning that at least the basics of routing policies are known.
If things go wrong the IRR is a perfect reference as long as data are properly registered. Then, it may also be used for building configurations.
Even though in general nobody is obliged to register routes and policies, many big providers demand that their peers properly register. This information is then actually used to install filters at least on the boundary routers.
How to check?
Routing information on the Internet and registry data have different formats. To compare both sets
and analyze the lists.
What to check?
directly from the Internet
