Reverse DNS Lookup
Convert IPv4 or IPv6 addresses into reverse DNS names and query their PTR records. Copy names, view TTLs and export results.
How to use Reverse DNS Lookup
Enter the requested address or domain and run the tool. Batch inputs accept one entry per line. Review each result and its status before exporting JSON or CSV.
DNS results are resolver snapshots and can change with caching and propagation. An empty answer differs from a nonexistent domain or a failed request. IP location is approximate and may identify a VPN or ISP location.
Data providers: Google Public DNS, Cloudflare DNS, and Country.is. Queries go directly from your browser to the selected provider.
