Well, if the router CAN run BGP, the feed from Cymru is only about 84 prefixes - not a lot of memory tied up there, is there? If the router isn't capable of BGP, someone earlier today was kind enough to post a script that they use to find changes to one of the BOGON lists and suggested an Expect script to automatically update their router. Probably a little advanced for most leaf sites, but for someone who's responsible for a larger network -- doesn't seem that bad.

How would this scale for say 200K routers? 2M? -Hank
