Why Use DNS Health Analyzer?

Spot misconfigurations before they cause downtime. Our tool automatically probes your infrastructure, validating essential records and ensuring your domain is routed perfectly across the internet.

Deep Zone Scanning

Automatically fetches and parses critical DNS records including A, AAAA (IPv6), CNAME, MX, NS, and TXT to provide a holistic view of your domain's routing configuration.

Mail Flow & Deliverability

Examines MX (Mail Exchanger) prioritization and verifies the existence of Sender Policy Framework (SPF) within TXT records to prevent email spoofing and bouncing.

Nameserver Redundancy

Evaluates your NS records to ensure you have a minimum of two active nameservers. This guarantees high availability and protects against single-point-of-failure outages.

Global Propagation Test

Choose between major public DNS resolvers like Google (8.8.8.8), Cloudflare (1.1.1.1), or Quad9 to verify that your recent DNS changes have propagated correctly worldwide.

Intelligent Health Scoring

Our proprietary algorithm calculates a health score from 0 to 100 based on standard RFC compliances. Get immediate feedback on whether your domain is Secure, Weak, or Critical.

Actionable Diagnostics

Don't just stare at raw data. Our tool translates technical errors into plain English, offering clear warnings and actionable steps to resolve misconfigurations instantly.
