Is the Pi-Hole even reasonably effective these days? > Nearly 70% of smart TVs and 46% of game consoles were found to contain hardcoded DNS settings - allowing them to simply ignore your local network’s DNS server entirely. https://labzilla.io/blog/force-dns-pihole

Sounds like we also need a list of IPs to null route

The workaround is already in use for ad hosting - serve all the content from one domain (or an IP) with services natted behind that, so if you block it, nothing works.

Yes; PiHoles are used for far more than just blocking smart TVs. The difference between browsing the web at my house and browsing away from home is so stark that it's almost not worth browsing most sites if I'm not behind it.

You can DNAT those requests at the router over to a Pi-Hole, unless they’ve upgraded to DoH

I know some of the LG domains should probably begin with a wildcard, as I’ve seen gb.lg etc that’s not in the list.

When I bought my first smart TV (mainly due to lack of dumb screens), immediately grabbed a Pi-Hole and started blocking everything I could find.

Also, one of the only occurrences where I’m skeptical even updating the tv software.

You can create port forward firewall rules to redirect any outbound DNS port 53 traffic. This will not work for DNS over HTTPS, which is going to be increasingly common for IoT I'd imagine. edit: method for this on pfSense: https://docs.netgate.com/pfsense/en/latest/recipes/dns-redir...

You could try this for DoH blocking. It probably needs help staying updated.

"#secure.netflix.com" "#api-global.netflix.com" "#appboot.netflix.com" These are commented out, but did someone really think the app would still work after blocking these? I get blocking ads, but I don't understand the mindset of someone who wants "smart" features but still wants to block everything.

1. It's actually very difficult to buy a non-smart TV. They usually cost more. 2. The comments also serve as a "no really, don't block these" reminder to enthusiastic contributors.

My TV has some sort of smart feature bullshit, but I just never gave it any wifi access. Avoids the issue entirely and I treat the TV as a monitor+speaker combo and nothing else.

Praise be the folks that curate these lists. Even without a pi-hole you can plug these into any firewall for your brand(s). More annoying is the 15 second "home menu" that pops up on my OLED every time it is turned on. I almost always forget to manually dismiss it before I set the remote down and there's no option I can find to disable it. I would pay a premium for a TV with no internet connection.

I can't be the only one that thinks this (DNS blocking) is an exceptionally poor solution to this problem. It's essentially whack-a-mole. You either A) don't allow your smart TV ip address to egress traffic to the internet or B) don't connect it at all. There are some domains in that list like the *.cloudfront.net that might change over time.

You're not wrong, but it is whack-a-mole, and this is one of our hammers.

The ideal solution is custom clients for every service. Why use their proprietary software? We should make our own software we can use to connect to their servers. That way we can make it do whatever we want.

I've read that LG TVs can be flashed with custom software.
