Our (soon to be recycled?) Samsung TV is sneaky bastard. It makes direct IP connections to tens of different addresses (pihole cannot block) and tries to use 8.8.8.8 (no, I'm not going to sell my DNS information to Google either).

Thanks to @mikrotik I could track these and block (I made simple python script to make reverse DNS query and generate commands to RouterOS directly.

Would you allow your TV to connect non-reversible IP addresses?

This is just ridiculous.
