DNS Lookup
Instantly retrieve A, AAAA, MX, TXT, and NS records for any domain name using our server-side DNS lookup path.
What This Tool Does
Our DNS lookup tool resolves common DNS records for any domain. You can check A records (IPv4), AAAA records (IPv6), MX records (mail servers), TXT records (SPF, DKIM, verification), and NS records (nameservers). Results come from server-side DNS resolution and are best used for quick diagnostics rather than authoritative trace analysis.
Common Use Cases
- Verify DNS propagation after making changes
- Debug email delivery issues by checking MX and SPF records
- Investigate domain configuration problems
- Check DKIM and DMARC records for email authentication
- Find all nameservers responsible for a domain
Frequently Asked Questions
What are the different DNS record types?
A records point to IPv4 addresses, AAAA to IPv6. MX records specify mail servers. TXT records hold text data like SPF policies. NS records list the nameservers delegated for the domain.
How long does DNS propagation take?
DNS changes typically propagate within 24-48 hours globally, but often much faster (minutes to hours). The actual time depends on TTL (Time To Live) values set on your records and caching by ISP resolvers.
Why might DNS lookup show different results?
DNS results can vary due to geographic load balancing, CDN configurations, or propagation delays. Different resolvers may cache records at different times, showing temporarily inconsistent results.
