NXDomain Data - Where is it stored?

We are looking for someone who understands NXDomain (NXD) data and where it now gets stored in Chrome and Edge or for someone to research this and figure it out. It used to be stored in a user’s History in their browser, but it no longer is. We want to be able to see this data. We just want to know where this data is stored, at this time. Do you know?
