Even if you do that, there’s some devices (Chromecast, Google Home) that have Google’s DNS hardcoded and ignores the servers passed by DHCP.

What happens if you set your firewall to block 8.8.8.8 and 8.8.4.4?

You can use an iptables rule on your router to rewrite the address to your custom server, which I have done specifically because Google devices were ignoring DHCP.

Something like...

iptables -t nat -A OUTPUT -p udp --dport 53 -j DNAT --to x.x.x.x:53

...should work, and repeat for tcp

It bricks the device. See these previous discussions.

This is terrible. What prevents them from doing the same to android phones and tablets?
