Start with a few domains to see A, AAAA, MX, NS, and TXT records in a structured table.

How to use this Bulk DNS Checker

Paste domains into the input box, choose the DNS record types you want to inspect, and run the lookup. The checker normalizes common inputs, removes duplicate domains, and queries DNS records through public DNS over HTTPS resolvers without requiring an account.

Use the results to confirm whether websites resolve, identify mail routing through MX records, review nameserver delegation, and spot TXT records used for SPF, DKIM, ownership verification, and platform integrations. For larger market research, connect these checks with NewDomainData product articles and sample categories to move from a small DNS sample to a full domain universe.

What the results mean

A successful result means at least one selected record type returned usable DNS data. A partial result means the domain responded for some selected record types but failed or returned no data for others. An error result means every selected lookup failed, timed out, or returned no records.

Privacy and European Data Notice

How this tool handles data

This Bulk DNS Checker runs DNS lookups from your browser through public DNS over HTTPS. The domain list you enter is used only to perform the lookup you requested and to render results in your browser.

Local browser storage

The most recent five lookup lists are stored in your browser localStorage so you can repeat common checks. You can clear this data at any time by using your browser site-data controls or the Clear button before closing the page.

European privacy principles

The tool is designed around data minimisation, transparency, and user control. It does not require an account, does not ask for personal data, and does not place the core lookup behind a subscription wall.

External resources

Cards marked as NewDomainData resources open the NewDomainData website in the normal browser flow. Once you leave this tool, the destination website's own terms, privacy policy, and cookie notices apply.
