Re: DID Range Enumeration

[Chris Reining <creining () securepipe com>]

I am not aware of any public resource that would provide you with this
information, CMIIW. It would make sense to do fingerprinting of their
phone ranges starting with a known number. Call every +/- 25th phone
number from the original and see who answers. This way you should be able
to discover where their block starts and ends. This poses a problem if 
they have multiple blocks assigned, but google should be able to reveal 
phone numbers associated with them.
