Frequently Asked Questions
How many domains can I check at once?
You can check up to 20 domains in a single bulk DNS lookup. Enter one domain per line in the text area and click Lookup All. All domains are resolved in parallel for fast results. If you need to check more domains, simply run multiple lookups.
What does the bulk DNS lookup check?
The bulk DNS lookup checks A records (IPv4 addresses), MX records (mail servers), SPF records (email sender authorization), and DMARC records (email authentication policy) for each domain. This gives you a quick overview of DNS and email security configuration across multiple domains at once.
Why did some domains fail?
Domains can fail for several reasons: the domain does not exist or has not been registered (NXDOMAIN), the authoritative DNS server is unreachable, the domain registration has expired, or there is a network connectivity issue. Failed domains are highlighted with an error message in the results table.
Can I export the results?
Yes, you can export the full bulk DNS lookup results in JSON, CSV, or plain text format. Click the Export button above the results table to download the data in your preferred format. This is useful for auditing DNS configurations across multiple domains or sharing results with your team.
Is the bulk lookup free?
Yes, the bulk DNS lookup tool is completely free to use with no signup required. The tool is rate-limited to prevent abuse, but normal usage is unrestricted. You can check up to 20 domains per request as many times as you need.
