Find missing hits in IP ranges Updated +Created
All IP ranges have some holes in them for which we don't have a domain name.
It is because there was nothing there, or just because we don't have a good enough reverse IP database?
It is possible that DomainTools could help with a more complete database, but its access is extremely expensive and out of reach at the moment.
Censys is another option that would be good to try.
Putting 140 USD into WhoisXMLAPI to get all whois histories of interest for possible reverse searches would also be of interest.
IP and DNS metadata Updated +Created
Some dumps from us looking for patterns, but could not find any.
Sources of whois history include:
When that data comes in JSON format as from whoisXMLAPI, we are going to just dump it in github.com/cirosantilli/media/blob/master/cia-2010-covert-communication-websites/whois.json
The vast majority of domains seem to be registered either via domainsbyproxy.com which likely intgrates with Godaddy and is widely used, and seems to give zero infromation at all about the registrar.
A much smaller number however uses other methods, some of which sometimes leak a little bit of data:
Big question: webmasters.stackexchange.com/questions/13237/how-do-you-view-domain-whois-history DomainTools also has it.
How on Earth did did Citizen Labs find what seems to be a DNS fingerprint??? Are there simply some very rare badly registered domains? What did they see!
