Hi, noob here.
What type of ads do routers with adblock manage to filter that normal browser extensions cannot? Thanks
A network "ad block" is just a DNS level block. If a Roku TV tries to reach ads.roku.net or whatever, the router can simply refuse to forward the request.
This is actually really useful beyond ad blocking. You can block known malicious sites as well.
They block ads from phone apps, which is amazing.
Works wonders for all the ads on apps targeted toward kids.
