How to Perform a DNS Lookup
- 1
Enter a domain name
Type or paste a domain name into the input field (e.g., example.com). You do not need to include http:// or www -- just the bare domain name. - 2
Select the record type
Choose the DNS record type you want to query: A for IPv4 addresses, AAAA for IPv6, MX for mail servers, CNAME for aliases, NS for name servers, TXT for verification and policy records, or SOA for zone authority data. - 3
Run the lookup
Click Lookup DNS to query Google's public DNS servers via DNS-over-HTTPS. Results appear instantly in a formatted table showing the record name, type, data, and TTL value. - 4
Review and compare results
Examine the returned records to verify your configuration. Check that A records point to the correct IP, MX records list the right mail servers with proper priorities, and TXT records contain valid SPF, DKIM, or verification tokens.
Common Use Cases for DNS Lookup
Domain Migration & Hosting Changes
Email Delivery Troubleshooting
Domain Verification for Third-Party Services
Security Auditing & Reconnaissance
Why Use DNS Lookup?
DNS Lookup is a free browser-based tool that queries the Domain Name System to retrieve A, AAAA, MX, CNAME, NS, TXT, and SOA records for any domain. Every query runs through Google's public DNS-over-HTTPS API directly from your browser, giving you the same globally propagated view that end users see worldwide. No command-line tools, no installation, no signup -- just type a domain, select a record type, and get results in seconds.
System administrators and DevOps engineers use DNS Lookup to verify hosting configurations, troubleshoot DNS propagation after record changes, and confirm that name server delegations are correct. Email administrators rely on MX and TXT record queries to diagnose delivery issues caused by missing SPF records, broken DKIM signatures, or misconfigured DMARC policies. For security professionals, DNS records reveal the infrastructure behind a domain -- pair this tool with the DNS Security Scanner to check DNSSEC status, or the SSL Certificate Checker to verify that HTTPS is properly configured.
DNS Lookup works well alongside other FindUtils network and security tools. Use the IP Address Lookup to geolocate the IPs returned in A records, the Email Validator to test addresses on domains whose MX records you have verified, or the Security Headers Analyzer to audit the HTTP security posture of the servers your DNS points to. All queries are private -- FindUtils does not log, store, or track the domains you look up.
How It Compares
Command-line tools like nslookup and dig are powerful but require terminal access and familiarity with their syntax. FindUtils DNS Lookup provides the same core data in a clean web interface that works on any device with a browser. Results are displayed in a formatted table with record type, data, and TTL columns, making it easy to scan and compare without parsing raw output.
Compared to other online DNS lookup tools, FindUtils queries Google's DNS-over-HTTPS endpoint directly from your browser rather than routing requests through a backend server. This means your domain queries never touch our infrastructure, providing stronger privacy than tools that proxy requests through their own servers. The tool is completely free with no usage limits, no accounts, and no ads -- making it ideal for quick checks during development, migrations, and security audits.
