Développeurs de logiciels Check domain availability (Available/Taken) for any TLD with confidence scoring, SSL certificate inspection, and IP resolution. Uses 5+ sources in parallel — RDAP, WHOIS (TLD-specific patterns for 30+ ccTLDs/gTLDs, IANA fallback for unknown TLDs), authoritative DNS NS lookup as GDPR tiebreaker for .de/.eu/.at/.ch/.es, DNS A/AAAA, HTTP reachability, and TLS certificate validation. Returns a clear binary verdict; when Taken, inline includes registrar, expiration date (or note if registry redacts under GDPR), nameservers, server IPs, and full SSL cert details. Single-domain or bulk-async (30 domains in ~10s). Stateless, stdlib-only, runs identically on Linux, macOS, and Windows. Use when the user asks if a domain is free/taken/available/registered, wants WHOIS or RDAP info, SSL certificate details, or to resolve a URL/domain to its server IPs. Triggers — "is X.com free", "check this domain", "bulk domain check", "SSL cert of X", "what IP does X resolve to", "domain availability", "ist X.de frei", "domain prüfen"
