Your web browser is just one piece of software on your network capable of displaying ads and collecting data

I thought this requires permission to a router. Can you do this say at an dorm or apartment where internet is provided for you through a portal

Even easier, configure your device to use an ad block DNS resolver. Control D has free ones: controld.com/free-dns
