DNS Propagation Checker

Check DNS record propagation across 5+ global DNS servers instantly. Verify how your DNS changes have propagated worldwide with real-time analysis, TTL tracking, and comprehensive server coverage.

About DNS Propagation Checking

What is DNS Propagation?

DNS propagation is the process by which DNS record changes spread across the global network of DNS servers. When you update DNS records, it takes time for these changes to propagate to all DNS servers worldwide, typically ranging from a few minutes to 48 hours.

Why Check DNS Propagation?

  • Verify DNS Changes: Confirm that your DNS record updates have propagated globally
  • Troubleshoot Issues: Identify which regions or servers haven't received updates yet
  • Monitor Performance: Check response times from different global locations
  • Ensure Consistency: Verify that all servers return the same DNS records
  • Plan Migrations: Monitor DNS changes during website or email migrations

How to Use This Tool

  1. Enter Domain: Type your domain name without http:// or www
  2. Select Record Type: Choose the DNS record type you want to check
  3. Advanced Options: Optionally select specific DNS servers or regions
  4. Check Propagation: Click the button to test across global servers
  5. Analyze Results: Review the propagation status and server responses

Example Use Cases

  • Website Migration: Check A records after pointing to new hosting
  • Email Setup: Verify MX records for new email providers
  • Security Records: Confirm TXT records for SPF, DKIM, or DMARC
  • CDN Configuration: Validate CNAME records for content delivery networks

Understanding the Results

Propagation Percentage

Shows what percentage of DNS servers have received your DNS updates. 100% means full propagation.

Consistency Check

Indicates whether all responding servers return identical DNS records. Inconsistency may indicate partial propagation.

TTL (Time To Live)

Shows how long DNS records are cached. Lower TTL values mean faster propagation of future changes.

Response Times

Displays how quickly each DNS server responds, helping identify performance issues in different regions.

Status Indicators

Success - Server responded with DNS records Error - Server failed to respond or returned an error

Pro Tips

  • Lower TTL Before Changes: Reduce TTL values 24-48 hours before making DNS changes
  • Check Multiple Record Types: Verify all relevant record types (A, MX, TXT, etc.)
  • Monitor Regional Differences: Some regions may propagate slower than others
  • Use Advanced Selection: Test specific servers if you're targeting particular regions
