DNS TOOL
Bulk DNS lookup
Check multiple domains against this site’s DNS resolver. Maximum 20 names per request.
DNS results
Run secure bulk DNS lookups for up to 20 domains or IP addresses. Results are resolved through this website rather than a third-party API.
How to use the Bulk DNS Lookup Tool
- Enter domains or IP addresses manually, or upload a CSV file.
- Select one or more DNS record types.
- Run the lookup, review the results, or download them as a CSV file.
Supported records: A, AAAA, MX, NS, CNAME, TXT, CAA, SOA, PTR, and SRV. SPF policies are returned as TXT records because SPF is no longer a standalone DNS record type.
