Products that do what A free curl API for IP data (we scan the IPv4 space in <24h) does
The curl API for WorldIP is now live and completely free to use. You can hit it right from your terminal: curl worldip.io — returns information about your requesting IP. curl worldip.io/8.8.8.8 — returns details on any specific IP. The main differentiator here is that we aren't just wrapping another provider's API and reselling their data. We built and run our own global infrastructure capable of scanning the entire IPv4 space in about a day. Happy to answer any questions about the scanning infrastructure or the stack!

Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.

Hi HN, I wanted to share this simple python app that you can host using App engine and get a free geoip service. It's pretty easy to limit it to the free quota and run without costs. You can't query for a specific IP address but it becomes super useful if you can make that request from the user's side (browser, app, etc). It only has access to lat, long, city, country, ip address but I find those to be the most useful data points. Hope this helps.

We've just launched an opensource golang `ipinfo` cli that lets you quickly and easily get IP address data from the cli. You can lookup geolocation, isp, carrier & vpn status for a single IP (in much the same way you can by `curl ipinfo.io`) but there's a bunch of additional functionality, including: - bulk lookups of IPs - summarize IPs (so get top ASNs, cities etc from a ton of IPs) - grepip subcommand to grep for IPs (v4, v6 and bogon flags available) - map command to map a bunch of IPs And more! See https://github.com/ipinfo/cli for more details and installation…

I am Abdullah from IPinfo. We have finally launched our API service that supports an unlimited amount of requests to fetch IP to Country and ASN database. It is free to use. https://ipinfo.io/lite Try out this token for the next several to check out the API service: a6c2e5328296f5 https://api.ipinfo.io/lite/8.8.8.8?token=a6c2e5328296f5 https://api.ipinfo.io/lite/me?token=a6c2e5328296f5 - The API system is built using Node.js from the ground up but we are currently moving our backend to Rust. We processed over 2 trillion requests last…

Hey HN, I built uncurl.dev to scratch my own itch: I kept getting curl commands in API docs, bug reports, or Slack messages and wanted a quick way to visualize, run, and debug them without firing up Postman or writing code to dissect them. It was also sometimes painful to create a test page specifically for non-tech users to consume an API. I originally vibe-coded this over a weekend just to make it easier for myself to debug API requests shared as curl commands. It slowly grew into something I found surprisingly useful in my workflow, so I decided to clean it up and share it. uncurl.dev…

IPDetective collects data from about 60+ different sources such as official cloud provider endpoints and public VPN/Proxy/Tor/Bot net lists. Then aggregates this data into a fast and easy to use API that can be integrated into applications or scripts easily. IPDetective started as a hobby project for my other hobby projects :) and I decided to wrap a simple website around and offer it as a service. Let me know what your thoughts, if you find value in this service or if you have any feature requests.

Hey! I'm a solo developer having fun learning Go. I have a side hustle and wanted to implement currency localization. I could use existing IP databases, but hosting on serverless is slow. So I built my own. I was surprised how fun it can be to use Go, and it's fast. Thankfully, Go's speed makes up for my dodgy code. Anyway, I'd love to get some feedback on my website/API. After a few weeks of testing and losing money on ads, I'm confident it's very reliable. This isn't a promo. It's basicly free (30k lookups/month), so there's no need to pay. Any advice or tips on how to grow and…
