There's a lot of online documentation about passive DNS. Here's one example > Passive DNS is a historical database of how domains have resolved to IP addresses over time, collected from recursive DNS servers around the world. It has been an industry-standard tool for more than a decade. > Spamhaus’ Passive DNS cluster handles more than 200 million DNS records per hour and stores hundreds of billions of records per month, providing you with access to a vast lake of threat intelligence data. https://www.spamhaus.com/resource-center/what-is-passive-dns... | ||

> collected from recursive DNS servers around the world Yes, of course, because those DNS servers are literally receiving the queries, eg "receiving the data". Again, there is nothing "leaking" here, that's like saying you leak what HTTP path you're requesting to a server, when you're sending a HTTP request to that server. Of course, that's how the protocol works! | ||
