Do DNS have a specific protocol? Is it possible to block any DNS query on my network that doesn’t ask my pihole?

>Is it possible to block any DNS query on my network that doesn’t ask my pihole?

...until they force all dns requests through DoH.

We have an LG with WebOS. Quite good actually, the remote is also very good, the browser is good, the apps work well.

The magic pointer ROCKS

Except you can't shut the thing off, which means I can't have the remote anywhere near me or I'll bump it and make the pointer pop up.

This isn't difficult: TVs should not be "smart". TVs should be incredibly dumb. They should be screens for displaying stuff. That's it. Nothing else. No network connection of any kind, no apps, no software beyond that necessary to do basic setup of how that screen works: brightness, input selection, etc.

You could get a smart TV and just not connect it to the internet. If you were really paranoid, you could disconnect/snip the wifi antenna. At least my TV still allow firmware updates via USB, so you may not lose that. Not that it'd matter much if you weren't using any smart features, but they do still provide things like improving compatibility with devices (recently HDMI 2.1). I have a bigger issue with VR headsets.…

No need to disconnect anything - all these TVs have manually Configurable IP Addresses, just set it and the gateway to 1.1.1.1 or something and it’ll never be able to talk to another device.

DNS is on port 53. So block outgoing port 53 except to your own DNS server. Likewise for DNS Over TLS (DoT), on port 853. The problem is DoH, which uses the same port as https (443) and so is harder to block.

Counterpoint: smart TVs are great. My LG has replaced almost every other thing that used to be in my media room. It is my streaming music box (I can target it for casting from my favorite iOS app, and I can use the interface on it for browsing my home network storage if I want). It has Netflix, Amazon, YouTube, Hulu, Disney, Vudu, Google TV, and every other damn thing on it. It has voice search, so I just say the nam…

Seconded on the LG WebOS. Hated smart/dumb TVs (Toshiba, Samsung, Sony) until I stumbled onto LG's WebOS. Speedy, works as expected, has most of the streaming apps. I thought the MagicRemote mouse thingy is going to be a gimmick but it's suprisingly nice to use.

Oh, and the checkboxes to disable some of the spying are buried on an industry-standard level of assholeiness, so that's good.

Disagree. My 75 yo parents still have a dumb tv. They have different remotes for cable, sound, blue ray player ( some smart apps), fire tv, and apple tv. Their life is not easier because of this, they don't watch what they want when they want because it takes minutes to get to a different source. I know what I'm getting them for Christmas

> I know what I'm getting them for Christmas

A TV with a good panel and a separate smart stick? :D

Really, that's the best choice. Always has been.

My neighbour called me because his Google apps (particularly, Youtube) stopped working on his smart TV. It's a cheap HiSense or something.

Still on warranty, but the store won't do anything as the hardware is fine, and they say the manufacturer is responsible for software updates. Which have stopped coming.

I'm pretty sure he didn't quite understand my "apps are Google property and they need to be updated every few months but this company stopped doing that" explanation, but anyway, he now has a dumb TV in the kitchen, and he specifically bought it so the wife could find recipes online, log in to Facebook and watch Youtube.

I told him to just get an Android computer stick, which will work just as well and last way longer. At the very least, it can be manually updated, unlike the built-in software.

I highly recommend that anyone who buys IoT devices, including smart TVs, gets a router or access point that supports multiple SSIDs and VLANS.

You can segregate your IoT devices from the rest of your stuff. You can even give a VLAN per device if you really want to, although it's probably not worth the effort.

I have 3 VLANs: one for my home network where my computers are, one for my security system, and one for the rest of my IoT devices. I don't even trust my Roomba on my home network!

I have a Unifi Dream Machine, but there are a few other consumer products that can achieve this kind of setup. If you have basic knowledge of how to use a computer, you can follow some YouTube tutorials about how to set up VLANs and firewall most of your devices from reaching your home computers.

I’m responsible for a bunch of IoT hardware, and every firmware spec I write includes a note on not using the DNS servers provided via DHCP. While sure there are companies explicitly doing this to avoid filtering, at least in my case it’s because a significant proportion of DHCP servers are configured to send DNS to your ISP, and ISP provided DNS is almost universally terrible. They’ll ignore TTLs, rewrite NXDOMAIN r…

> and ISP provided DNS is almost universally terrible. They’ll ignore TTLs, rewrite NXDOMAIN responses into the IP address of their ad-laced web search, and occasionally just highjack every single query to send you to a page saying you’re approaching your bandwidth quota Universally? Perhaps in the US? But IoT devices are sold worldwide. While I do run my own recursive resolver I checked my ISP's and they're behaving…

My ISP in the UK returns NXDOMAIN for records pointing to 10. ips. I had to go through a lengthy process to have that issue fixed with them. Their support had no idea, and was trying to tell me it's nothing to do with them.

That freezer is 1.5 decades.

Yes, and wouldn't really surprise me if freezers with the same design can still be found in stores today.

They can, but they will lack features like vacation mode, cleaning mode, fault sensors, and door ajar audio notification.
