Subdomain Scanner

Uncover active subdomains for any domain in seconds. Parallel DNS resolution across common patterns with automatic wildcard detection.

How It Works

Fast, accurate subdomain enumeration without false positives.

All subdomain candidates are tested simultaneously using concurrent workers. Results in seconds, not minutes.

Before scanning, we probe for wildcard DNS records. False positives are automatically filtered.

Our dictionary covers infrastructure, cloud, DevOps, marketing, and security subdomains.

Each query has a strict timeout to prevent slow nameservers from blocking the scan.

Each discovered subdomain returns its DNS record type with all associated IP addresses.

Find forgotten staging servers, admin portals, and development environments exposed to the internet.
