DNS Health Check
Check DNS configuration health and verify essential records. Use the DNS Lookup Tool to query specific records, or Reverse DNS Lookup for PTR validation.
What this Health Check validates
An opinionated audit: health score, DNS basics, email security (MX, SPF, DMARC), nameservers, optional CAA and TTL sanity. Issues include severity and how to fix.
- Score 0–100 and status (Good / Needs Attention / Critical)
- Email: MX, SPF, DMARC presence and policy
- DNS basics: A/AAAA, NS, SOA
- Security: CAA, nameserver count
- Performance: TTL extremes
Tip: Enter a domain to run the audit. Raw DNS records are in a collapsible section after the results.
What we check
We audit your DNS for missing or misconfigured records, nameserver consistency, and common email/security settings so you can fix issues before they affect users.
Email DNS basics (SPF/DMARC/MX)
- MX – Points to your mail servers; required for receiving email.
- SPF (TXT) – Lists allowed sending IPs/hosts to reduce spoofing.
- DMARC (TXT) – Policy for handling failed SPF/DKIM; helps protect your domain from phishing.
Recommended fixes
Address any “missing” or “invalid” items in the report: add or correct MX, SPF, and DMARC as needed. Use our DNS Lookup Tool to inspect current TXT and MX values.
