Incoming links: WhoisXMLAPI
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.
Some dumps from us looking for patterns, but could not find any.
Sources of whois history include:
- whois-history.whoisxmlapi.com/ from whoisXMLAPI. Notably they also have historical reverse WHOIS... tools.whoisxmlapi.com/reverse-whois-search but it needs credits. TODO we need to squeeze this a but further at some point.
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.

- differentviewtoday.com: tools.whoisxmlapi.com/whois-history-search kind of empty no name
but presumably these are the names of employees of the company? We are yet to see two identical names however, which also suggests fake names.

- plugged-into-news.net: Godfrey Hubbard. Searching tools.whoisxmlapi.com/reverse-whois-search for two terms "Godfrey" "Hubbard" gives a small list of 20 domains including plugged-into-news.net. They all appear to have both words in them. Searching just "Hubbard, Godfrey" has only 3 hits:so it seems to match the strings exactly!

- godaddy without domainsbyproxy.com: a few of the websites are registered in Godaddy without domainsbyproxy. These might be the ones that gives out the most information:

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!
They don't have an actual online judge system, all problems simply have an integer or floating point solution and they just check that you've found the value.
The only metric that matters is who solved the problem first after publication, e.g.: projecteuler.net/fastest=454. The "language" in which problems were solved is just whatever the user put in their profile, they can't actually confirm that.
Project Euler problems typically involve finding or proving and then using a lemma that makes computation of the solution feasible without brute force. As such, they live in the intersection of mathematics and computer science.
List of just the solution values:
Code solutions by individuals:Basically no one ever had the patience to solve them all. What we need is a collaborative solution.
Problems are under CC BY-NC-SA: projecteuler.net/copyright
How problems are chosen:
projecteuler.net says it started as a subsection in mathschallenge.net, and in 2006 moved to its own domain. WhoisXMLAPI WHOIS history says it was registered by domainmonster.com but details are anonymous. TODO: sample problem on mathschallenge.net on Wayback Machine? Likely wouldn't reveal much anyways though as there is no attribution to problem authors on that site.
www.hackerrank.com/contests/projecteuler/challenges holds challenges with an actual judge and sometimes multiple test cases so just printing the final solution number is not enough.
whoisXMLAPI whois history squeezed further and better understood Updated 2025-04-16 +Created 2025-04-15
I also squeezed whoisXMLAPI harder but nothing much came out.
The vast majority of domains use domainsbyproxy.com privacy which does not seem to leak any information on their whois except dates which appear well spread out.
I did notice however that some of the sites are registered with Network Solutions, LLC and a few others in Godaddy without domainsbyproxy.com. These have names of people on them, and I did as many whoisXMLAPI searches for those names as I had the patience for.
A few had another known hit on the results, and a new hit domain came out of this: rolling-in-rapids.com which as it turns out has no Wayback machine archive, but does have a CQ Counter archive which allowed me to confirm the hit page style. That one was found by reverse searching for the registrant of
alljohnny.com, "Glaze, L." on tools.whoisxmlapi.com/reverse-whois-search and its IP matches 65.218.91.9 from welcometonyc.net.If anyone would like to donate 140 USD to dump into whoisXMLAPI I could dump all the known hit histories and have a look at them to see if anything else comes out on reverse search.
