Testing the reachability of (new) address space

The Internet was originally designed to provide connectivity from every node to every other node. However, policies can impede this connectivity [1]. This is especially true for newly allocated address space. Some Internet Service Providers (ISPs) simply do not realize that the status of previously unallocated address space has changed, and they continue blocking that space. Therefore, it would be desirable to test whether filters block newly apportioned address space before it is allocated to ISPs and/or end users.
