What Hacker News says?
Just check https://ipinfo.io/ to see how close your IP points to your location. For most targeted content the city is good enough. And honestly if I'm one of 1 million people it's ok.

HN discussionWow ! I would never have guessed icanhazip.com got such an enormous amount of requests per day ! I wonder how this site/service achieved such a notoriety ? I am really not trying to diminish the author work but since it is something pretty simple to build and I know there are lots of others alternative I wonder what makes people choose this one over an other like let's say : http://ipinfo.io/ip https://test-ipv6.com…

HN discussionHmm. So I don't know if this means anything, but I was googling for the IP address and wound up at https://ipinfo.io/160.116.88.235 which says hostname: visit.keznews.com. When you go to that hostname, it's one of the best phishing sites I've ever seen. They dynamically inserted my ISP's logo (Spectrum) and tried to do a phishing attempt: https://i.imgur.com/C9HQw1c.png The full non-clickable URL: https://us.poonsta…

HN discussionOur detection model at ipinfo is largely based on behavior models of IP addresses. We have 700 servers around the world from which we run internet measurement, allowing us to reliably determine which IP addresses are VPNs or proxies. These measurements are largely ping/traceroute data, which enable us to estimate a number of different things most importantly IP location data. If you are interested in what kind of ot…

HN discussionI launched http://ipinfo.io a few years ago. The API gets over 250 million requests a day, and is profitable. I left my job at CTO of calm.com at the end of last year to focus on it fulltime. There's more of the backstory here: https://getputpost.co/from-side-project-to-250-million-daily...

HN discussionI work for IPinfo. If you're on a residential connection, the geolocation of that IP address is likely to be accurate up to the ZIP code area. We have generalized hints of location information from over 70 different sources. Then we aggregate them and we map this information based on population density in the geographic region. Sure, our data is becoming more granular, but it's not granular enough to detect individu…

HN discussionI started https://ipinfo.io as a side project, and then ran it fulltime as a one-person SaaS app for over a year. We're now a team of 8, profitable, and growing quickly. We're still 100% bootstrapped, and I have zero plans to raise any outside funding. We started with a simple IP geolocation API, which now handles over 20 billion API requests per month. We've added new data to that service, such as IP type classific…
