Object detection model.
You can get some really sweet pre-trained versions of this, typically trained on the COCO dataset.
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.
Their data is also quite disjoint from the data of the 2013 DNS Census. There is some overlap, but clearly their methodology is very different. Some times they slot into one another almost perfectly.
You can only get about 250 queries on the web interface, then 250 queries per free account via API.
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.
They check your IP when you signup, and you can't sign in twice from the same IP. They also state that Tor addresses are blacklisted.
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.
They also normalize dots in gmail addresses, so you need more diverse email accounts. But they haven't covered the
.gmail vs .googlemail trick.We do API access to IP ranges with this simple helper: cia-2010-covert-communication-websites/viewdns-info.sh, usage:e.g.:
./viewdns-info.sh <apikey> <start-ipv-address> <end-ipv-address>./viewdns-info.sh 8b890b00b17ed2d66bbed878d51200b58d43d014 66.45.179.187 66.45.179.210For 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'Very curiously, their reverse IP search appears to be somewhat broken, or not to be historic, e.g.We've contacted viewdns.info support and they replied:This is likely not accurate, more precisely it likely only works if it was the last IP address, not necessarily a current one.
- viewdns.info/iphistory/?domain=vuvuzelanews.com hits 74.116.72.246 in 2011, later moved to others
- viewdns.info/reverseip/?host=74.116.72.246&t=1 however does not contain
vuvuzelanews.com
The reverse IP tool will only show a domain if that is it's current IP address.

Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01These are basically technically minded people that Ciro Santilli feels have similar interests/psychology to him, and who write too much for their own good:
- cat-v.org
- gwern.net. Dude's a bit overly obsessed with the popup preview though! "new Wikipedia popups (this 7th implementation enables recursive WP popups)" XD
- settheory.net by Sylvain Poirier
- HyperPhysics
- Orange Papers
Maybe one day these will also be legendary, who knows:
Another category Ciro admires are the "computational physics visualization" people, these people will go to Heaven:

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
