Privacy & Security

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.

Stacked bar chart showing DNS client activity over 24 hours, with a large spike near 20:00 reaching over 600, then elevated activity through 08:00.

I find it interesting that my Pi-hole blocks 10-20% of DNS requests made when nobody is home. Average of 200 DNS requests every 10 mins when nobody is home, and 20-40 of those are some form of tracking. 😠

The top blocked domain that my Pi-Hole is protecting me from every day is api.segment.io. That isn’t a web browser thing that 1Blocker could even block. It is API calls embedded, I suspect, in iOS Apps. I love having multiple layers of surveillance blocking!

Table of top blocked domains on a Pi-Hole, led by api.segment.io with 1070 hits, followed by mobile-collector.newrelic.com with 680.

“You’re one of 772,904,991 people pwned in the Collection #1 data breach.” That is a shockingly large amount of credentials compromised. Good blog post describing it. Very happy I use unique, random passwords with 1Password!
