DNS diagnostics preview
DNS Lookup Tool
A planned diagnostic for reviewing the public records used by websites, nameservers, verification, and email.
Prepared tool preview
This tool is not live yet and does not generate a result. It remains noindex and is excluded from the sitemap and main navigation until the backend can perform safe, rate-limited checks.
No request is sent and no result is fabricated in this preview.
Planned useful output
- A, AAAA, CNAME, MX, TXT, and NS records
- TTL and authoritative-answer context
- Clear empty and DNS-error states
Backend work required
Implement a DNS resolver service with normalized domain validation, record-type restrictions, rate limits, timeouts, response-size limits, and structured errors.
