ℹ️ About Bulk DNS Lookup
The Bulk DNS Lookup tool is an efficiency utility for IT professionals managing large portfolios of domains or investigating complex network issues. While standard DNS tools lookup one domain at a time, this utility allows you to query multiple domains for a specific record type (like A, MX, or TXT) in a single operation.
This is extremely useful for auditing DNS propagation, verifying that all your subdomains point to the correct IP addresses, or extracting SPF/DKIM records from a list of partners or competitors. By consolidating the results into a single view, it saves time and provides a clearer overview of your digital assets' DNS health.
📖 How to use Bulk DNS Lookup
- 1. List the domains you wish to query, separated by commas.
- 2. Select the DNS record type you are interested in (e.g., 'MX' for mail servers).
- 3. Click 'Run Tool' to perform the parallel lookups.
- 4. Analyze the resulting list of IP addresses or record values for each domain.
❓ Frequently Asked Questions
How many domains can I check at once?
You can check up to 20 domains in a single request.
Does this tool use my local DNS cache?
No, it performs live queries against standard global DNS resolvers to ensure you see current records.
Can I check multiple record types at once?
Currently, you must select one record type per bulk request. To check multiple types, run the tool once for each (e.g., once for A, once for MX).
