Reverse IP lookup maps an IP address back to its PTR (reverse DNS) hostname and network details. It reveals who owns or operates the IP — useful for identifying hosting providers, CDNs, and cloud infrastructure.

This tool returns the reverse DNS hostname (PTR record), whether the IP belongs to a hosting/datacenter provider, the organization name, and ASN. It does not enumerate all domains hosted on a shared IP — for that you would need a dedicated reverse-IP database service.

Useful for security research, network troubleshooting, and verifying whether traffic is routed through a CDN, VPN, or cloud provider.
