just thinking what would happen if I block connection to Ads services in my router...

That's pretty much what a pi-hole is. According to my friends who use a pi-hole to filter their connection, it makes almost everything ad-free

Also https://nextdns.io/ on the cloud. I run my ios devices with no ads thanks to this honest service. Can i modify the DNS resolver on a samsung tv (i do not intend to have one ever)

you can but if it cant resolve it will fallback to googles resolver automatically. At least this is what happened on my model.

Yes, this happens. But then you make a firewall rule to route outbound port 53 traffic that doesn’t come from the Pihole to go back to the Pihole. It gets rather elaborate.

I built my own router with a raspberry pi. I installed pi-hole and use that as a dns resolver. I then use an iptables rule to NAT / forward all dns traffic on port 53 to the pi-hole resolver, similar to how ISPs often intercept dns requests. This prevents IOT devices from bypassing the dns server configured via my DHCP. Letting pi-hole block the requests helps prevent errors from dns request timeouts.

This method works really well.

DNS over HTTP has screwed this up.

I'm just waiting for smart devices to start doing that instead, forcing me to set up full SSL filtering until they start doing encrypted SNI :/

True, although then I’d lose trust in the devices and wouldn’t want to use them by that point anyway.

I set my router dns to use the custom values nextdns provides for my account, which enabled it for the entire residence. It was fun to see the flotsam in the nextdns logs. I love this service.

Ads on my Samsung TV is the entire reason I decided to finally pi-hole my entire home network. It's wonderful. No ads on my TV and much less on my tablet, phone and PC. Too bad pi-hole doesn't stop Youtube ads.

The only complaint is from my wife who sometimes Googles stuff and clicks on the top result, which is often an ad and will end up blocked. She now has to scroll down a bit to the real results.

The pi-hole will be bypassed by hard-to-kill DNS-over-HTTPS, however.

Yea force it to go through a proxy with your own ca and filter from there.

Key pinning and Expect-CT will prevent that.

It will not prevent firewalling... but the TV might not work.

my samsung tv always tops the charts on most blocked connections on my pi-hole, its not even close. it is disgusting.

Same thing on my Philips TV (Europe). It tries to make a lot of calls to *.imrworldwide.com https://better.fyi/trackers/imrworldwide.com/

It does exactly what you would hope, at least for Samsung TVs. Ads disappear, other functions are not affected.

Upon discovering the ads I was gonna return mine for a comparable LG, until I learned LG also have ads—at least this way I can pretend I'm not being taken for a ride.

At the time I didn't have any external devices capable of 4K Netflix or YouTube; now I do I should factory reset the TV and set it up without network access,

The article says LG removed the ad.

Damn, maybe I should have done the return then.

A panasonic tactical technical response team is enroute to your house, ETA 15 minutes.

Now I have to fill my TV with Tannerite, too?!
