This graph of DNS requests by client at our cabin is a good example of how metadata and privacy interact. When did we get there? How many people were there? All reasonable things that you could derive from this metadata.
@jthingelstad Extra credit: What in the house is sending a big network request every 10 minutes and what other thing every 15? I’m guessing TVs.
@esjewett so looking at Pi-Hole DNS activity in your house during periods when nobody is home is an upcoming hobby of mine. I hope to restore more of my privacy by combining that with the new Pi-Hole v5 ability to group blocklists by device. The good news is that most of these "smart" devices seem to handle surveillance failure silently.
