Its not even just providers. If it were, it'd be relatively easy to just find and call each NOC. You're likely to have bogon issues with few large providers. It's mostly smaller providers and end user networks...some of which are quite large or high profile.
Do what I did and give people a way to test connectivity from both affected and unaffected space and setup a 'hall of shame' page listing the IPs/networks that are behind broken filters. Can someone identify the *benefits* of using bogon lists for unallocated space? It appears that it only hurts connectivity, but does not help in any significant way to enhance security.
Possibly, whoever are the vendors of software that recommends this practice (and authors of security handbooks) should be show the error of their ways? -alex
