How to tell a real Google-NotebookLM from a fake

  1. The user-agent contains Google-NotebookLM. On its own this proves nothing: fakes copy it.
  2. The visit’s IP address is inside Google’s published lists (google-user, google-user-google, below). If it isn’t, it’s a fake.
  3. Or: the address’s reverse DNS name ends in .google.com or .googleusercontent.com, and that name resolves back to the same address.
