Lookup DNS records for any domain with this free tool. Enter a domain like nvidia.com or openai.com to see its A, MX, TXT, NS, and other DNS records instantly.
DNS lookups are essential for troubleshooting email delivery, verifying domain configuration, checking DNS propagation after changes, and auditing security settings. This tool is optimized for speed, returning results in seconds without requiring signup.
When you enter a domain, we query authoritative DNS servers to retrieve the current records. The Domain Name System acts as the internet's phone book, translating human-readable domain names into IP addresses and storing configuration data.
Record Types: A records point to IPv4 addresses, AAAA to IPv6, MX defines mail servers, TXT holds text data (including SPF), NS specifies nameservers, SOA contains zone administration info, and CNAME creates domain aliases.
This tool skips DKIM selector discovery (which requires testing many possible selectors) to deliver faster results. For DKIM analysis, use Advanced DNS Lookup or DKIM Lookup.
A DNS lookup queries the Domain Name System to retrieve DNS records for a domain. It translates domain names into IP addresses and reveals mail servers, nameservers, and other configuration data stored in DNS records like A, MX, TXT, and NS.
This tool queries the most common DNS record types: A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (text records including SPF), NS (nameservers), SOA (start of authority), and CNAME (canonical name aliases).
DNS lookups help troubleshoot email delivery issues, verify domain configuration, check if DNS changes have propagated, identify a domain's hosting provider, and audit security settings like SPF records.
DNS Lookup queries common record types quickly. Advanced DNS Lookup adds DKIM selector discovery, MX server IP resolution with geolocation, and deeper email authentication analysis — but takes longer to complete.
Yes, DNS Lookup is completely free with no signup required. For bulk lookups across multiple domains, check out DNS Explorer which offers enterprise-scale DNS scanning.
