HN discussionBig fan of what articles? On https://incolumitas.com/ or on https://ipapi.is/ ? Great idea with latency triangulation, I used latency information for a lot of things, especially VPN and Proxy detection. But I didn't assume you can obtain that accurate location. I am honestly impressed. But latency triangulation with 600 servers gives some very good approximation. Nice man! Some questions: - ICMP traffic is penalised…

HN discussionthe last one is not vague, it is clearly a hosting provider: https://www.instagram.com/atomohost/?hl=en But I picked just one faulty classification of ipinfo.io, that's not fair, I know. I only wanted to point out that what you are doing is exactly the same as https://ipapi.is/ is doing and that we both make mistakes ---- You are using the 700 measuring servers to interpolate geolocations of IP addresses, right?

on “IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks”In general ipinfo.io has the best data and the best product out there in the IP API niche. It is what it is. Your data is the most accurate and most updated. Hosting detection is a finite process, meaning that there is a finite amount of hosting providers out there to detect after all. Challenge lies in staying up to date. So maybe we can make a compromise and state that ipinfo.io is likely a bit better than ipapi.i…

on “IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks”Hey, I am happy to see you here! What do you think of the event? I think you might find it interesting how these IPs were submitted. I would love to hear your thoughts. In our previous interaction, I mentioned that I learned about CGNAT-based web scraping from your article on your personal blog. In this event, people took it to a whole other level. People were churning carrier IPs by the hundreds to win a pair of so…

on “IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks”In case anyone needs a all around good IP api with excellent threat intelligence that is not that expensive as IPinfo is, I suggest to use https://ipapi.is/ https://ipapi.is/ is not as good in regards to geolocation, but our hosting detection is more advanced and https://ipapi.is/ is much cheaper...

on “IPinfo's IP Hunt: 2.2M IPs submitted over 3 weeks”There are tools such as https://ipapi.is/ that can be used to geolocate any IPv4 and IPv6 address in the world. Sometimes those tools are not extremely accurate, but usually they are accurate to the city level.
