Level3 pull information from a number of sources, including RIPE where 
we register our routes. One of the nice things about their setup is you 
can query a whois interface to check the filter generation:

e.g. (to pick someone else's AS-MACRO at random)

whois -h filtergen.level3.net RIPE::AS-DEMON
