About DNS Lookup
DNS Lookup is a powerful tool that queries DNS servers to retrieve domain name records. It uses Cloudflare's DNS-over-HTTPS API to look up A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, CAA, and PTR records. You can also check DNS propagation across multiple providers.
How to Use
Enter a domain name, select the record types you want to query, and click Lookup. Results are displayed in a color-coded table. You can check propagation across Cloudflare, Google, and Quad9 DNS servers, copy results, or export as JSON.
Common Use Cases
- Verifying DNS configuration after making changes to domain records
- Checking DNS propagation across different DNS providers worldwide
- Troubleshooting email delivery by inspecting MX and TXT records
- Verifying SSL certificate and security settings via CAA records
- Debugging website connectivity issues by checking A and AAAA records
