This tool runs entirely in your browser – nothing you type is sent to Auburn AI or stored anywhere. We cannot see your data.
A page cannot query DNS itself without sending a request to a third party. Instead of quietly doing that, this builds the exact commands to run yourself, plus a one-click link to a public DNS-over-HTTPS debug page.

About this tool
DNS Lookup queries the Domain Name System for a given domain and returns its associated DNS records, including A records, CNAME records, MX records, and more. It is useful for developers, sysadmins, and anyone who needs to verify how a domain resolves across the public internet without opening a terminal. The tool shows you the IP addresses and other record data tied to a hostname in plain, readable form.
Reach for this tool when you are troubleshooting email delivery problems, confirming that a DNS change has propagated, checking whether a domain points to the expected server, or investigating an unfamiliar domain before trusting it. It saves time compared to running command-line tools like nslookup or dig, especially when you are on a machine where those tools are unavailable.
How to use it
- Type or paste the domain name you want to query into the input field.
- Select the DNS record type you need, such as A, MX, CNAME, or TXT.
- Click the Lookup button to send the query to public DNS resolvers.
- Review the returned records, including IP addresses, TTL values, and hostnames.
- Switch record types using the dropdown to check other DNS entries for the same domain.
- Copy any result row you need for documentation or further investigation.
Pro tips
- Query the TXT record type to verify SPF, DKIM, and DMARC entries that control email authentication for a domain.
- A very low TTL value in the results often means the domain owner is preparing for a DNS change or migration soon.
