Cloud IP Ranges
Cloud IP Ranges is a website I built that collects public IP data from different cloud providers, standardises the data, and make them available to download and use. I built this because I've been developing some products where I don't want any traffic from cloud providers (to avoid scrapping and crawling, mainly). The service is free to use and free to use! Hope you all find it useful.
Cloud IP Ranges launched on March 28, 2025 with 7 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
What it does
Download up-to-date IP ranges (CIDRs) for 81 cloud providers, CDNs and crawlers — AWS, Azure, Google Cloud, Cloudflare and more. Free, in txt, csv and json.
Current CIDRs for 81 cloud providers, CDNs, and crawlers — one place, consistent formats, updated daily. Every provider publishes its CIDRs in a different place and format. This service pulls them into one page — txt, csv, and json with stable URLs you can curl from a script, firewall, or cron job. All download links are permalinks - they always return the latest data, perfect for scripts and CI/CD pipelines. Choose from TXT (simple lists), CSV (with metadata), or JSON (structured data) formats. Combine providers with /download.txt?providers=aws,azure . # Download AWS IPs and block them with iptables wget -O aws_ips.txt https://cloud-ip-ranges.com/download/aws.txt while read ip; do iptables…from cloud-ip-ranges.com

IP Guide – Info on IP addresses, Networks, and ASNs2023 · ip.guide · ▲363Hey 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.
