Frequently Asked Questions
What is RDAP and how is it different from WHOIS?
RDAP (Registration Data Access Protocol) is the modern, standardized replacement for legacy WHOIS services. It delivers structured, machine-readable JSON queries over secure HTTPS with standardized error handling and internationalized domain support.
How does DNS over HTTPS (DoH) work in this suite?
DNS over HTTPS routes DNS queries through encrypted HTTPS connections to public resolvers like Google Public DNS or Cloudflare. This prevents ISP eavesdropping, cache poisoning, and man-in-the-middle record spoofing during diagnostic lookups.
What determines the Security Posture Grade?
Security scores are calculated by inspecting critical HTTP protection headers including Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, and X-Content-Type-Options to grade vulnerability mitigation against clickjacking and injection.
Why is server ping latency slightly variable?
Latency measures round-trip time from your browser to the destination edge server. Variations happen naturally due to CDN anycast routing, client network hops, geographic server distance, and transient internet packet congestion.
Can I inspect subdomains and apex domains?
Yes, the suite automatically extracts the apex domain for RDAP registrar lookups while resolving explicit DNS records, response headers, and latency for specific subdomains like api.example.com or blog.example.com.
