DNS Kit - Domain & Email Check

DNS Kit is the all-in-one network diagnostics tool for developers, sysadmins, and IT professionals. Check any domain's DNS records, scan email configurations, and monitor DNS propagation across 23+ global servers — all from your phone.

▸ DOMAIN HEALTH DASHBOARD
Enter any domain and instantly get a health score. DNS Kit checks your DNS records and email configuration, giving you a clear percentage score so you know exactly where things stand. Save multiple domains and track their health over time.

▸ DNS RECORD LOOKUP
Query all major DNS record types — A, AAAA, CNAME, MX, TXT, SOA, PTR, and more. See TTL values, IP addresses, and full record details in a clean, readable format.

▸ EMAIL HEALTH SCANNER
Run deep scans on your domain's email setup. DNS Kit checks:
• SPF records — verify sender authorization
• DKIM records — confirm email signing
• DMARC policies — check email authentication
• MX records — validate mail server configuration
• Mail server connectivity — DNS resolution, reverse DNS (PTR), hostname matching, SMTP connection, TLS support, and open relay detection
• Blacklist status — check if your mail server is listed

Get a detailed report with pass/fail indicators for every check, plus a full SMTP transcript for debugging.

▸ DNS PROPAGATION CHECKER
Changed your DNS records? Track propagation across 23 servers worldwide. See a global map showing which servers have updated and which are still serving old records. Filter by record type — A, AAAA, CNAME, MX, TXT — and watch propagation happen in real time.

▸ SAVED DOMAINS
Save up to 50 domains for quick access. Each domain shows its health score and last checked time, so you can monitor your entire portfolio at a glance.

Built for professionals who need reliable DNS diagnostics on the go. No ads. No fluff. Just the tools you need.
