What DNS record types can I query?
Our API supports all major DNS record types: A (IPv4), AAAA (IPv6), MX (mail servers), TXT (text records), CNAME (aliases), NS (nameservers), SOA (start of authority), PTR (reverse DNS), SRV (services), and CAA (certificate authority).
How fast are DNS lookups?
Most DNS queries complete in under 100ms. We use distributed DNS resolvers globally to ensure fast, reliable responses regardless of your location.
Can I check email server configuration?
Yes! Query MX records to find mail servers, then check TXT records for SPF, DKIM, and DMARC configuration. This is essential for email deliverability analysis.
How do I verify domain ownership?
Many services require adding a TXT record for verification. Use our API to check if the verification record has been added correctly before proceeding with setup.
Can I monitor DNS propagation?
Yes! Query DNS records periodically to check if changes have propagated. Compare results from different resolvers to see propagation status across regions.
What is TTL and why does it matter?
TTL (Time To Live) determines how long DNS records are cached. Lower TTLs allow faster propagation of changes but increase DNS query load. Our API returns TTL values with each record.
Can I query DNS records for subdomains?
Absolutely! Query any subdomain just like a regular domain. This is useful for verifying CDN configuration, checking subdomain ownership, and infrastructure auditing.
How do I check SPF records for email?
Query TXT records for the domain and look for entries starting with "v=spf1". Our API returns all TXT records, making it easy to validate email authentication setup.
Is there a free tier for testing?
Yes! Our free tier includes generous API limits for development and testing. Upgrade to a paid plan when you need higher throughput or production-level reliability.
Can I use this for network diagnostics?
Yes! DNS lookups are fundamental to network troubleshooting. Check if domains resolve correctly, verify nameserver configuration, and diagnose connectivity issues.
