What is DNS Report Checker?
A DNS Report Checker is a comprehensive diagnostic tool that analyzes your domain's DNS configuration and provides a detailed health report with scores, issues, warnings, and recommendations. Unlike simple DNS lookup tools, a DNS report checker evaluates DNS best practices, security configurations, redundancy, and performance optimization.
Our free DNS Report Checker examines A records, AAAA records, MX records, TXT records (SPF, DKIM, DMARC), NS records, SOA records, and TTL values to provide an overall DNS health score from 0-100 with actionable recommendations for improvement.
What Does DNS Report Check?
🌐 A & AAAA Records
IPv4 and IPv6 address configuration, redundancy, load balancing setup.
📧 MX Records
Mail server configuration, backup MX setup, priority levels.
🔒 Email Security
SPF, DKIM, DMARC records for email authentication and anti-spoofing.
🌍 Name Servers
NS record count, redundancy compliance, geographic distribution.
⚙️ SOA Record
Zone authority information, serial numbers, refresh intervals.
⏱️ TTL Values
Time-to-live optimization for performance and flexibility.

📚 Frequently Asked Questions
Q: What is a good DNS health score?
A: A score of 90+ (Grade A) indicates excellent DNS configuration. Scores 80-89 (Grade B) are good with minor improvements needed. Below 70 requires attention.
Q: Why is my DNS score low?
A: Low scores typically result from missing records (MX, SPF, DMARC), insufficient name servers (less than 2), or no IPv6 support. Check the critical issues and warnings sections for specific problems.
Q: What are SPF, DKIM, and DMARC?
A: These are email authentication protocols. SPF specifies authorized mail servers, DKIM adds digital signatures to emails, and DMARC defines policies for handling failed authentication. All three protect against email spoofing.
Q: How many name servers should I have?
A: RFC 1034 requires at least 2 name servers for redundancy. We recommend 3-4 name servers for optimal reliability and geographic distribution.
Q: What is a good TTL value?
A: For production sites, 300-3600 seconds (5 minutes to 1 hour) is optimal. Lower values increase DNS queries but allow faster updates. Higher values reduce load but slow propagation.
Q: Is this DNS report checker free?
A: Yes! Completely free with unlimited checks. No registration or payment required. Get comprehensive DNS health reports instantly.
