Great article, I did know about this at all... DNS is super interesting. I wrote dug, a cli tool I made to help visualize DNS 'propagation' but is a great learning tool. Similar to dig and dog, but specifically for querying or watching large numbers of DNS servers at once. https://github.com/unfrl/dug https://github.com/unfrl/dug https://dug.unfrl.com https://dug.unfrl.com
