Global DNS Checker

DNS records control how your domain behaves on the internet, from where email gets delivered to which server handles web traffic. When changes are made to these records, they do not update everywhere at once. The Global DNS Checker from FileReadyNow lets you look up any DNS record type for any domain and check its values across 15+ locations worldwide, so you can confirm propagation status, diagnose misconfigurations, and understand your domain setup at a glance.

What This Tool Does

Enter a domain name, select the record type you want to inspect, and the tool queries DNS servers from multiple geographic locations and returns the results. You can check a single record type in detail or run a comprehensive lookup that returns all available record types at once. The results show the values returned from each location so you can immediately identify propagation gaps or inconsistencies between regions.

Supported Record Types

The checker supports all standard DNS record types:

• A: Maps a domain to an IPv4 address
• AAAA: Maps a domain to an IPv6 address
• MX: Specifies mail exchange servers for incoming email routing
• TXT: Text records used for SPF, DKIM, domain verification, and other configurations
• CNAME: Aliases one domain name to another
• NS: Name server records that delegate DNS authority for the domain
• SOA: Start of Authority record containing administrative information about the zone
• PTR: Reverse DNS lookup mapping an IP address back to a domain name
• SRV: Service location records used for VoIP, messaging, and other protocols
• CAA: Certificate Authority Authorization records controlling which CAs can issue SSL certificates

Common Use Cases

• DNS Propagation Monitoring: After updating a domain's DNS records, check whether changes have propagated to servers in different countries and regions.
• Email Configuration Verification: Confirm MX, SPF (TXT), and DKIM records are correctly set before troubleshooting email delivery issues.
• Domain Transfer Validation: Verify that NS records have been updated correctly after transferring a domain to a new registrar or DNS provider.
• SSL Certificate Troubleshooting: Check CAA records to confirm the correct certificate authority is authorized to issue certificates for the domain.
• Competitor and Research Lookups: Inspect the DNS configuration of any public domain to understand its hosting provider, mail service, CDN setup, or verification records.

What to Expect from the Results

Results are returned from multiple global DNS resolvers and displayed by location. Differences between locations are normal during propagation and typically resolve within 24 to 48 hours after a DNS change. Once propagation is complete, all locations should return identical values. If discrepancies persist beyond the expected TTL, they may indicate a misconfiguration that needs investigation.
