Free DNS Lookup Tool - Query Domain Name Records Online

Our DNS Lookup tool lets you query and inspect the DNS records of any domain name instantly. The Domain Name System (DNS) is often called the "phonebook of the internet" -- it translates human-readable domain names (like google.com) into IP addresses that computers use to identify each other on the network. This tool helps you examine A, AAAA, MX, TXT, NS, CNAME, and SOA records in a single query.

Whether you are a system administrator troubleshooting connectivity issues, a developer verifying domain configuration, or a security professional auditing email authentication records, this tool provides a fast and reliable way to inspect DNS records without needing command-line tools like dig or nslookup.

The tool supports all major DNS record types and displays results in a clean, organized format with color-coded record type badges, copy-to-clipboard functionality, and query time measurements. Simply enter a domain, select which record types to query, and get comprehensive DNS information in seconds.

Key Features

7 record types supported: Query A, AAAA, MX, TXT, NS, CNAME, and SOA records in a single lookup
Selective record queries: Choose exactly which record types to query for focused results
Quick test domains: One-click buttons for popular domains like Google, GitHub, Cloudflare, and Amazon
Smart domain normalization: Automatically strips protocols, paths, and www prefixes from input
Color-coded results: Each record type is visually distinguished with unique color badges
Copy to clipboard: Copy any individual DNS record value with a single click
Query time display: See exactly how long each DNS lookup takes in milliseconds
Record count display: Instantly see how many records were found for each type
SOA detail parsing: Displays primary nameserver, admin email, and serial number for SOA records
MX priority display: Shows mail server exchange names alongside their priority values

How to Use the DNS Lookup Tool

Enter a domain name: Type the domain you want to query (e.g., example.com) into the input field, or use a quick test button
Select record types: Choose which DNS record types to query by clicking the type buttons (all are selected by default)
Click Lookup: Press the Lookup button or hit Enter to perform the DNS query
Review results: Examine the color-coded results organized by record type with record counts
Copy values: Click the copy icon next to any record to copy its value to your clipboard

Use Cases

Domain troubleshooting: Diagnose DNS propagation issues, configuration errors, and connectivity problems
Email security auditing: Verify SPF, DKIM, and DMARC records in TXT records to ensure email authentication is correctly configured
Hosting migration planning: Document all existing DNS records before transferring a domain or switching hosting providers
SSL certificate verification: Check A and CNAME records to confirm domains point to the correct servers before issuing certificates
CDN configuration: Verify CNAME records are correctly pointing to CDN endpoints like Cloudflare or AWS CloudFront
Mail server setup: Confirm MX records are correctly configured with proper priority values for email routing
Domain ownership verification: Check TXT records for domain verification tokens from services like Google Workspace or Microsoft 365
Competitive analysis: Examine which hosting providers, email services, and CDNs competitors are using

Frequently Asked Questions

Is this tool free?

Yes, the DNS Lookup tool is completely free to use with no limits on the number of queries, no registration required, and no premium features locked behind a paywall.

Is my data secure?

Yes. DNS lookups query publicly available information. We do not log your queries or store any personal data. The domain names you look up are only used to perform the DNS query.

What is the difference between A and AAAA records?

A records map a domain to an IPv4 address (e.g., 142.250.185.78), while AAAA records map to an IPv6 address (e.g., 2607:f8b0:4004:800::200e). Both serve the same purpose but for different IP address formats.

Why do I see no records for some types?

Not all domains have every record type configured. For example, a domain without a mail server will have no MX records, and a domain that uses A records directly will have no CNAME records.

How long does DNS propagation take?

DNS changes can take anywhere from a few minutes to 48 hours to propagate globally, depending on the TTL (Time-To-Live) values set on the records. Lowering TTL before making changes can speed up propagation.

Can I look up any domain?

Yes, you can look up DNS records for any publicly registered domain name. The tool automatically normalizes input by stripping protocols, paths, and www prefixes.

Tips & Best Practices

Check all record types when troubleshooting: Select all record types for a comprehensive view of a domain's DNS configuration
Verify MX records for email issues: If emails are not being delivered, check MX records to confirm mail servers are correctly configured with proper priorities
Look for SPF records in TXT: Email deliverability problems often stem from missing or misconfigured SPF records in TXT entries
Document records before migration: Always perform a full DNS lookup and save the results before making changes to domain hosting or nameservers
Lower TTL before making changes: Reduce TTL values 24-48 hours before planned DNS changes to speed up propagation
Use the query time to diagnose speed: Unusually slow query times may indicate DNS server issues or network problems
