I shared an early version of this tool a while back, but the backend has been completely rewritten this weekend.
The Problem: The #1 issue I saw wasn't just 'missing' records, it was the 10-DNS-Lookup Limit. People add HubSpot, Salesforce, and Google, and suddenly their email breaks because of nested includes.
The New Solution (v2):
I added a 'Fix It' engine that performs a recursive DNS scan. It dives into every include:, resolves the IPs, and flattens them into a single, valid list that bypasses the lookup limit.
New Features:
Deterministic Output: I locked the LLM temperature to 0.0 so it acts as a logic engine, not a creative writer.
Safety Toggles: You can now toggle between SoftFail (~all) and HardFail (-all) instantly to see the diff.
Visual Diff: Shows exactly which IPs are being pulled from where.
It’s still free, no ads, no login. Would love to know if the flattening logic holds up against your most complex enterprise domains."

But your ‘lookups’ count doesn’t factor-in nested lookups incurred by ‘include’ directives. Isn’t that the whole point of this? And your ‘security grade’ seems to be incongruous with the look-up count.
And could you detail your use of LLMs in this? It’s straightforward DNS queries, right?
I don’t see options for the ‘safety toggles’ you mentioned.
