Some TV manufacturers have gotten wise to this (sigh) and started hard-coding their DNS lookup IPs.

I remember having to set up a firewall rule to drop or reroute all DNS queries through my PiHole. What a pain in the ass to have to jump through hoops for a device I paid over $1k for.

Is there a list of such manufactures? Don't want to accidentally buy one of their products.

Well that's easy enough to filter - just nat all outgoing traffic to UDP/53 to your preferred device.

Of course google and other spy companies are pushing DNS over HTTPS, so once that becomes popular in these devices, you're screwed - you simply have to block all traffic (in which case you won't be able to watch netflix/disney/whatever using that device. For a TV that's fine, as you have a PC plugged into it, for now)

Not only the DNS lookup IPs are getting hardcoded, even the ads themselves may be shipped on the device, in case it cannot update the ads (e.g. no internet connection).
