Instantly identify which cloud provider owns any IP address — and exactly which region, service, or network it belongs to.
~/.zshrc or ~/.bashrc, then use: i 52.52.52.52IP range data is fetched directly from each provider's official published source and kept up to date automatically.
Every major cloud provider publishes a list of the IP address ranges they use — for their services, regions, and edge networks. This tool looks up any IP against all of those lists simultaneously.
AWS, Azure, GCP, Cloudflare, Oracle, and DigitalOcean all maintain public JSON or text files listing every CIDR block they own. They update these when they add new regions or services.
An IP address is matched against all known CIDR blocks (e.g. 52.52.0.0/15). The most specific matching block wins, revealing the region and service.
Identify cloud-hosted traffic in firewall logs, verify that an IP belongs to a known provider, or debug routing issues across multi-cloud environments.
Use the REST API directly from scripts or pipelines: GET /api/<ip> returns a JSON response with provider, region, service, and the matching prefix.
