I've found pinging a polite email to the whois contact on the ASN - sometimes- gives useful results, but not always. Be aware that you're not only dealing with router black-holes, but seemingly some people have applied bogon filtering to their BIND name servers also. If you can provide a non bogon IP within the same AS, it can be useful for the person at the other end-- shows them they have a problem. -Shane On 20/10/2009, at 4:51 PM, Matthew Walster wrote:

A pingable address in the problem range would help people to quickly evaluate whether they have a problem in their network or upstreams...
The router has the address "109.68.64.1" - saves giving out customer's IP.
Does anyone have any recommendations for dealing with BOGON space that hasn't been defiltered by networks? Any ideas how to get people to update filter lists?
