Detailed Overview
Whether you’re rolling out a new site, changing name servers, or validating email deliverability records (SPF, DKIM, DMARC), Global DNS gives you the signal you need. The script aggregates answers from multiple resolvers so you can verify actual propagation rather than a single-resolver cache. WHOIS and RDAP lookups are formatted for clarity, making registrar, expiry, and status checks painless for support teams and clients.
Built with modern PHP and cURL, the codebase is lightweight and extensible. Add resolvers, customize result cards, or integrate with your existing admin portal. Host it once—use it forever.
