Launch ToolDiagnostic Notice
This sandbox does not store any information you query or input. Diagnostic commands, sockets, and audits run dynamically and output directly to the browser view. No telemetry records are captured on this node.
Domain WHOIS Lookup
Retrieve domain names registration details and IP allocation assignments from global WHOIS servers.
DNS Zone Dig
Query global DNS nameservers for zone configurations, aliases, text parameters, and MX mail routes.
SMTP Diagnostics
Simulate SMTP transactions directly from the server to diagnose MX routes and authentication flows.
Run the diagnostic tool to watch the SMTP transaction log in real time.
Security Headers Auditor
Inspect the HTTP headers returned by a target application to verify security policies and configurations.
Secure Password Generator
Generate high-entropy random passwords or rememberable sentence passphrases on the client.
Random Password Settings
Easy-to-Remember Passphrase
