DNS Lookup
Query DNS records for any domain to view A, AAAA, MX, TXT, NS, and other record types.
About DNS Lookup
DNS (Domain Name System) translates domain names into IP addresses. Different record types serve different purposes:
- A Record - Maps domain to IPv4 address
- AAAA Record - Maps domain to IPv6 address
- MX Record - Specifies mail servers for the domain
- NS Record - Lists authoritative nameservers
- TXT Record - Holds text data (often for verification)
- CNAME Record - Creates an alias to another domain
What is DNS Lookup?
DNS (Domain Name System) translates human-readable domain names like "google.com" into IP addresses that computers use to communicate. A DNS lookup queries authoritative nameservers to retrieve various record types associated with a domain. Understanding DNS records is essential for website administration, email delivery troubleshooting, and network security analysis.
Our DNS lookup tool retrieves all major record types in a single query: A records (IPv4 addresses), AAAA records (IPv6 addresses), MX records (mail servers), NS records (nameservers), TXT records (verification and policy data), and CNAME records (domain aliases). This gives you a complete picture of how a domain's DNS is configured.
Understanding DNS Record Types
- A Record - Maps a domain to an IPv4 address (e.g., 93.184.216.34)
- AAAA Record - Maps a domain to an IPv6 address
- MX Record - Specifies mail servers responsible for receiving email for the domain
- NS Record - Identifies the authoritative nameservers for the domain
- TXT Record - Stores text data, commonly used for SPF, DKIM, and domain verification
- CNAME Record - Creates an alias from one domain name to another
Frequently Asked Questions
How long does DNS propagation take?
DNS changes typically propagate within 24-48 hours, though many updates are visible within 1-4 hours. The propagation time depends on the TTL (Time to Live) value set on the previous records and how quickly DNS resolvers around the world refresh their caches.
What is a DNS cache and how do I clear it?
A DNS cache stores recent DNS lookups locally on your device or network to speed up future requests. To clear it on Windows, run "ipconfig /flushdns" in Command Prompt. On macOS, use "sudo dscacheutil -flushcache". On Chrome, visit chrome://net-internals/#dns and click "Clear host cache".
Why do I have no DNS records for my domain?
If no records appear, the domain may not be registered, DNS may not be configured yet, or the nameservers may be unreachable. Check that your domain registration is active and that your nameservers are properly set at your registrar.
