Handily it's possible to query Level3's filters through a whois interface, for example:On Mon, 9 Jul 2007, Cat Okita wrote:As far as "needing a verification system", is there something deeply problematic about filtering your customers? It's a fine example of thinking globally and acting locally.That's what I'm curious about...this boils down to L3 not properly filtering Hanaro.Having recently turned up some L3 connectivity, I was happy to discover that they can use any of the routing registries as the source of their prefix filters. They told me the prefix filters are automatically constructed based on the RR of your choice...update the RR, and their filters will update that night, no need to bug them. Yay for that, wish everybody worked that way.But...why wasn't Hanaro being filtered? If the filters are being automatically generated, I would think they would just filter all of their peers regardless of number of prefixes etc.
whois -h filtergen.level3.net RIPE::AS25577 For some reason this doesn't work: whois -h filtergen.level3.net APNIC::AS9318 But this does, presumably this one is reading of an internal Level3 db: whois -h filtergen.level3.net AS9318 List of prefixes returned is: Prefix list for policy AS9318 = LEVEL3::AS9318 61.98.32.0/19 61.98.64.0/20 61.98.96.0/20 124.111.0.0/16 210.93.131.0/24 210.93.132.0/22 211.33.96.0/20 211.49.96.0/20 211.49.144.0/20 211.49.192.0/19 211.49.240.0/20 211.59.160.0/19 211.59.208.0/20 211.59.224.0/20 211.110.160.0/19 211.110.224.0/20 211.186.0.0/19 211.186.32.0/20 211.186.64.0/19 211.186.96.0/20 211.186.144.0/20 211.186.160.0/19 211.243.144.0/20 211.243.224.0/19 211.244.0.0/20 211.244.32.0/19 211.244.64.0/20 211.244.176.0/20 211.245.48.0/20 218.49.114.0/24 218.234.87.0/24 Sam
