Which Primary DNS to use to block updates on PS5?

Hello,

I followed Modded Warfare's video in preparation for the new JB.

Neither DNS he provided works – I connect to the internet without any errors and have access to Sony servers.

I tried:

45.56.67.85

62.210.38.117

I've heard that 127.0.0.1 also exists, but blocks web browser access.

Does anyone have a solution for this?

Thanks!
