D'oh.
But to be serious. The Wayback Machine contains a very large proportion of all sites. It does happen sometime that a Wayback Machine archive is missing or broken and cqcounter has the screenshot. But the Wayback Machine is still the most complete database we have found so far. Some archives are very broken. But those are rare.
The only problem with the Wayback Machine is that there is no known efficient way to query its archives across domains. You have to have a domain in hand for CDX queries: Wayback Machine CDX scanning.
The Common Crawl project attempts in part to address this lack of querriability, but we haven't managed to extract any hits from it.
CDX + 2013 DNS Census + heuristics however has been fruitful however.
We have dumped all Wayback Machine archives of known websites to: github.com/cirosantilli/cia-2010-websites-dump using ../cia-2010-covert-communication-websites/download-websites.sh. This allows for better grepping and serves as a backup in case they ever go down.
Accounts used so far: 6 (1500 reverse IP checks).
Their historic DNS and reverse DNS info was very valuable, and served as Ciro's the initial entry point to finding hits in the IP ranges given by Reuters.
Generic information about the website not specific on this project will be stored at: Section "viewdns.info".
Since this source is so scarce and valuable, we have been quite careful to note down all the domain and IP ranges that have been explored.
At news.ycombinator.com/item?id=38496244, the creator of the viewdns.info, "Hughesey", also stated that he'd able to give some free credits for public research projects such as this one. This would have saved up going to quite a few Cafes to get those sweet extra IPs! But it was more fun in hardmode, no doubt.
We do API access to IP ranges with this simple helper: ../cia-2010-covert-communication-websites/viewdns-info.sh, usage:
./viewdns-info.sh <apikey> <start-ipv-address> <end-ipv-address>
e.g.:
./viewdns-info.sh 8b890b00b17ed2d66bbed878d51200b58d43d014 66.45.179.187 66.45.179.210
For domain to IP queries from the API you should use "iphistory" viewdns.info/api/docs/ip-history.php:
curl 'https://api.viewdns.info/iphistory/?domain=todaysengineering.com&apikey=$APIKEY&output=json'
Just beware of the viewdns.info reverse IP bug, that really sucks and led to us missing a ton of domains.
This data source was very valuable, and led to many hits, and to finding the first non Reuters ranges with Section "secure subdomain search on 2013 DNS Census".
Hit overlap:
jq -r '.[].host' ../media/cia-2010-covert-communication-websites/hits.json ) | xargs -I{} sqlite3 aiddcu.sqlite "select * from t where d = '{}'"
Domain hit count when we were at 279 hits: 142 hits, so about half of the hits were present.
The timing of the database is perfect for this project, it is as if the CIA had planted it themselves!
dnshistory.org contains historical domain -> mappings.
We have not managed to extract much from this source, they don't have as much data on the range of interest.
But they do have some unique data at least, perhaps we should try them a bit more often, e.g. they were the only source we've seen so far that made the association: headlines2day.com -> 212.209.74.126 which places it in the more plausible globalbaseballnews.com IP range.
TODO can it do IP to domain? Or just domain to IP? Asked on their Discord: discord.com/channels/698151879166918727/968586102493552731/1124254204257632377. Their banner suggests that yes:
With our new look website you can now find other domains hosted on the same IP address, your website neighbours and more even quicker than before.
Owner replied, you can't:
At the moment you can only do this for current not historical records
This is a shame, reverse IP here could be quite valuable.
In principle, we could obtain this data from search engines, but Google doesn't track that entire website well, e.g. no hits for site:dnshistory.org "62.22.60.48" presumably due to heavy IP throttling.
Homepage dnshistory.org/ gives date starting in 2009:
Here at DNS History we have been crawling DNS records since 2009, our database currently contains over 1 billion domains and over 12 billion DNS records.
and it is true that they do have some hits from that useful era.
They appear to piece together data from various sources. This is the most complete historical domain -> IP database we have so far. They don't have hugely more data than viewdns.info, but many times do offer something new. It feels like the key difference is that their data goes further back in the critical time period a bit.
TODO do they have historical reverse IP? The fact that they don't seem to have it suggests that they are just making historical reverse IP requests to a third party via some API?
E.g. searching thefilmcentre.com under historical data at securitytrails.com/domain/thefilmcentre.com/history/al gives the correct IP 62.22.60.55.
But searching the IP 62.22.60.55 is empty and there's no historical data option?
Account creation blacklists common email providers such as gmail to force users to use a "corporate" email address. But using random domains like ciro@cirosantilli.com works fine.
Their data seems to date back to 2008 for our searches.
So far, no new domains have been found with Common Crawl, nor have any existing known domains been found to be present in Common Crawl. Our working theory is that Common Crawl never reached the domains How did Alexa find the domains?
Let's try and do something with Common Crawl.
Unfortunately there's no IP data apparently: github.com/commoncrawl/cc-index-table/issues/30, so let's focus on the URLs.
Hello world:
select * from "ccindex"."ccindex" limit 100;

Naive one for one index:
select * from "ccindex"."ccindex" where url_host_registered_domain = 'conquermstoday.com' limit 100;
have no results... data scanned: 5.73 GB
Let's see if they have any of the domain hits. Let's also restrict by date to try and reduce the data scanned:
select * from "ccindex"."ccindex" where
  fetch_time < TIMESTAMP '2014-01-01 00:00:00' AND
  url_host_registered_domain IN (
   'activegaminginfo.com',
   'altworldnews.com',
   ...
   'topbillingsite.com',
   'worldwildlifeadventure.com'
 )
Humm, data scanned: 60.59 GB and no hits... weird.
Sanity check:
select * from "ccindex"."ccindex" WHERE
  crawl = 'CC-MAIN-2013-20' AND
  subset = 'warc' AND
  url_host_registered_domain IN (
   'google.com',
   'amazon.com'
 )
has a bunch of hits of course. Data scanned: 212.88 MB, WHERE crawl and subset are a must! Should have read the article first.
Let's widen a bit more:
select * from "ccindex"."ccindex" WHERE
  crawl IN (
    'CC-MAIN-2013-20',
    'CC-MAIN-2013-48',
    'CC-MAIN-2014-10'
  ) AND
  subset = 'warc' AND
  url_host_registered_domain IN (
    'activegaminginfo.com',
    'altworldnews.com',
    ...
    'worldnewsandent.com',
    'worldwildlifeadventure.com'
 )
Still nothing found... they don't seem to have any of the URLs of interest?
Does not appear to have any reverse IP hits unfortunately: opendata.stackexchange.com/questions/1951/dataset-of-domain-names/21077#21077. Likely only has domains that were explicitly advertised.
We could not find anything useful in it so far, but there is great potential to use this tool to find new IP ranges based on properties of existing IP ranges. Part of the problem is that the dataset is huge, and is split by top 256 bytes. But it would be reasonable to at least explore ranges with pre-existing known hits...
We have started looking for patterns on 66.* and 208.*, both selected as two relatively far away ranges that have a number of pre-existing hits. 208 should likely have been 212 considering later finds that put several ranges in 212.

Many of the student exchange programs Ciro witnessed in the 2010's in Brazil were inefficient because they were requiring students to come back immediately after university or PhD in fear that those students will never come back.
This is useless, because you don't learn anything unique during university: the truly valuable knowledge is obtained when you work for several years as a postdoc in a world class research laboratory or as an engineer in a world class company.
Therefore, Brazil should learn from the Chinese exchange system, which lets students go do whatever they want, and once they are Gods of the domain, entices them back with great positions and pay as heads of laboratory back in China. Just don't do fraudulent stuff like this like China did, or else you will get a bad rep.
To help this university collaboration happen, we should create communication channels between exchange students and professors of the origin country who work on the same domain so that they can discuss the subject. For example, once Ciro Santilli wanted to contact some of his former teachers at the University of São Paulo about "advanced" topics he had been exposed to as part of his job. However, they didn't even reply to his email, and Ciro didn't know who else to contact. This must never happen. We need a way to informally contact several professors of a given domain informally, to increase the chances that at least one might be interested. It is pointless to just let students loose abroad and hope that they will bring things back to their home country: a more cohesive infrastructure is needed to nurture that.
There is basically one sane way to achieve these goals: the exchange programs must be organized at a national level, not in an ad-hoc per-university manner.
Another good idea is to have taxes that depend on your nationality alone and which only start collecting when you reach a very high amount of net worth. So e.g. if someone leaves the country and makes it big, then and only then does the Government starts clawing back the benefits of its investments in the person. Furthermore, such taxes could be reduced if the person brings some of the business back to the country. And mandatory taxes should be charged if the person decides to drop their nationality at some point.
The above points would also be greatly eased by having a national-level exchange program. E.g. in Brazil in the 2010's which Ciro experience, every university had different terms and conditions, which made everything a mess. Exchange programs must be treated as a unified federal policy.
Ciro actually had to return for just six months from the École Polytechnique to the University of São Paulo, to finish a course he had only done the generic Maths/Physics introduction to. Students from other Brazilian universities were forced to return for up to 3 years even to get their Brazilian diplomas! Ciro was lucky that his teachers understood the situation, and allowed him to develop online learning projects instead of his supposed control engineering projects, which hopefully will have led to changing the world with motivation one day. And for this, Ciro is eternally thankful.
This shows the complete and total lack of any Brazilian strategy to send its students abroad to really learn valuable things and then come back. There is no strategy at all. Things have just reached an equilibrium point of bureaucracies, Brazilian universities trying to bring students back to validate useless diploma pieces of paper, and foreign universities no caring about that, and just wanting the students to say abroad forever.
Ciro was once talking about why so few Brazilians go study abroad compared to the Chinese. Besides the likely true "there are a lot of Chinese" argument, his wife made another: good point Brazil is not so bad to live in, because you have good food and freedom, while China only has good food.
But Ciro still fells bad that so few of his University of São Paulo colleagues, who learnt automation and control engineering, are doing deep tech. Nor physical engineering. They have all basically become computer people like Ciro.
This is not their fault. They basically don't have a choice: all physical science and technology is done in rich countries.
Yes, someone has to implement the newest tech to improve local country efficiency in projects that will never spread abroad.
But who will be left then for the next big thing problems that would really make Brazil richer? 6 out of 30 person class ended up working on a gaming company at one point, even though they were not crazy passionate about the field! What could possibly be a worst investment for society?
This lack of technological innovation can also be clearly seen when you research investment options available in Brazil. Huge emphasis is put on fixed return financial products (often inflation adjusted) linked to base non-tech business such as housing market and agriculture. And when you look to the returns of the stock market on s&P 500-analogue backed exchange-traded funds, they do not seem obviously better, especially considering inflation and taxation benefits that exist for some of the other investment possibilities.
When the companies of a country are not clearly the best investment, you know that something is wrong. They are highly specialized money making machines, remember! And housing and agriculture are not such innovative markets where people can hugely influence efficiency.
When it is best to send students is a good question. Undergrad studies could be easily reproduced in poor countries if they had any intelligence at all, since even in rich countries laboratory usage is always limited. Masters and PhD are generally more valuable moments to send people out. The question is if the students will actually have a fighting chance without having been out, in particular in terms of language skills. Ciro feels that Masters are a good focus point for entry, as that is where PhD links are more actively done.
Open source video game by Ciro Santilli 37 Updated 2025-07-16
Why would anyone ever waste time playing a closed source game, when this will inevitably lead to endless hours of decompilation down the line when you want to:
Those who devote their time to the useless development of open source video games, before we even have decent open source development tooling, will, without a doubt, have their place in Heaven.
