Hi, my company has just been allocated some new IPv4 address space, and I want to do some sort of automated testing to find out any ASs out there that haven't removed the /8 it's on from their bogon list (the allocation to our local registry only occurred in November last year).
IMHO, if a network doesn't either update filters based on IANA notifications or follow Cymru BOGON, then they don't deserve to receive traffic from your network ;)
Has anybody attempted to do this? It is worth bothering? Currently I'm considering pulling out all the endpoint ASs out of the BGP table, finding at least one subnet for each of them and attempting to ping or reach other common ports on a single IP for each AS from our currently working address space, and then the new address space and comparing results.
Sounds like a major PITA. Why not tell us what the prefix is that you have, and we can ensure that our filters our clean? Probably easier asking a few 'NOGs than it is sweeping a few thousand prefixes. Steve
