How to block youtube ads on smart tv?

Question

Computer networks

In general, I have lg smart tv (10.172.12.25)
It is connected to the router (10.172.12.1/10.172.10.250)
There is also a server on the network 10.172.10.0/24
And the output router is 10.172.10.254 The
TV does not know the proxy settings, on the router there are no such settings. I would like to make ads.youtube.com resolve to 127.0.0.1
What are the solutions?

Answer 1

We flash the router on openwrt, there we create an entry ads.youtube.com 127.0.0.1
