What is a DNS health check?

A DNS health check analyzes your domain's DNS configuration to identify issues with nameservers, MX records, mail authentication (SPF, DMARC), PTR records, and overall DNS setup. It helps ensure your domain is properly configured for email delivery and web hosting.

How do I check my DNS records?

Simply enter your domain name in the search box above and click 'Analyze DNS'. DNSly.io will instantly check your nameservers, MX records, SPF, DMARC, SOA records, and provide a comprehensive health score with detailed validation results.

What is an MX record?

MX (Mail Exchange) records specify which mail servers handle email for your domain. They include priority values and hostname information. DNSly.io validates your MX records, checks for redundancy, validates PTR records, and ensures proper mail server configuration.

What is SPF and DMARC?

SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting & Conformance) are email authentication protocols that help prevent email spoofing and phishing. DNSly.io checks if these records are properly configured for your domain.
