How to Use DNS Lookup Tool
- 1
Enter a Domain Name
Type the domain name you want to look up in the input field. You can enter just the domain (e.g., 'example.com') without protocols or paths.
Tip:You can look up any publicly registered domain name. Subdomains like 'mail.example.com' are also supported. - 2
Select Record Types
Choose which DNS record types you want to query. By default, all common record types are selected for comprehensive analysis.
Tip:Different record types serve different purposes - A/AAAA for IP addresses, MX for email servers, TXT for verification and SPF records. - 3
View DNS Results
Click 'Lookup DNS' to retrieve and display all DNS records for the domain, organized by record type with detailed information and metadata.
Tip:Results show the record value, TTL (Time To Live), priority for MX records, and other relevant information for each DNS entry. - 4
Copy and Use Results
Use the copy buttons to quickly copy individual DNS records or export all results for documentation, troubleshooting, or migration purposes.
Tip:DNS information is useful for domain migration planning, email setup, and troubleshooting connectivity issues.

Frequently Asked Questions
What DNS record types can I look up?
You can look up A (IPv4), AAAA (IPv6), MX (mail exchange), TXT (text), CNAME (canonical name), and NS (name server) records for comprehensive domain analysis.
Why don't I see some DNS records for my domain?
Not all domains have all record types configured. For example, a domain might not have AAAA records if IPv6 isn't supported, or specific TXT records if certain services aren't configured.
How current are the DNS results?
DNS results are fetched in real-time from authoritative DNS servers, so you'll see the most current information available on the internet with live propagation status.
What does TTL mean in the results?
TTL (Time To Live) indicates how long DNS resolvers should cache the record before checking for updates. Lower TTL values mean faster propagation of DNS changes.
Can I look up private or internal domains?
This tool only works with publicly registered domain names that are accessible via public DNS servers. Internal, private, or localhost domains won't return results.
How can I troubleshoot DNS propagation issues?
Use this tool to check if your DNS changes have propagated. If you see old values, the changes may still be propagating or there might be caching issues with your local DNS resolver.

Use Cases & Applications
Domain Migration Planning
Check current DNS configuration before migrating a website to ensure all records are properly documented and transferred to the new hosting provider.
Email Server Configuration
Verify MX records to troubleshoot email delivery issues, confirm proper email server configuration, or set up new email services for a domain.
Domain Ownership Verification
Check TXT records for domain ownership verification when setting up third-party services like Google Workspace, SSL certificates, or CDN services.
Network Troubleshooting
Diagnose connectivity issues by checking if DNS records are properly configured, propagated across the internet, and resolving correctly.
Security Audit & Analysis
Examine SPF, DKIM, and DMARC records in TXT entries to verify email security configuration and prevent email spoofing attacks.
DNS Propagation Monitoring
Monitor DNS changes after updates to ensure new records have propagated globally and are being served by authoritative name servers.
