Stop Ads Before They Load

Your browser extension works. Everything else in the building is wide open. The phone shows ads inside apps, the television reports home to its manufacturer, and the smart devices that could never run a blocker are the ones talking the most. There is a way to filter for every device at once, and it works one layer down. Before anything connects, it has to turn a name into an address. Put a filter there and one machine, configured once, covers the whole network. This book gets you there without overselling it. You will learn what DNS actually does, how to choose and install the hardware, how to point your network at it, and how to manage blocklists without breaking services your household depends on. You will also be told the truth up front, in its own chapter: YouTube ads are not blocked, many apps still show advertising, some devices bypass the filter completely, and this is not a security product. What you get instead is far fewer trackers, protection for devices that cannot protect themselves, and real visibility into what your hardware talks to. One chapter is devoted entirely to the day it goes down and the whole house thinks the internet is broken, including a rollback you can perform in under a minute. By the end you decide what your devices are allowed to reach.
