How can we track the provenance of an IP address? Is there a magic RBL that lists the known IPs of commercial proxy services?
Having a problem with an "American" company who leases IPs from datacenters in U.S./Canada. But, they have no control over the IP space. They sub-rent the addresses to another company that uses it for anonymous proxy service.
