How does DNS affect the quality of your Gameplay?
I hope this is not too sensitive a topic and, if it is preferred to be moved to a more mainline forum, that's fine, but the purpose of the thread is to focus specifically on online gaming using the ATT Internet product, which is why I'm opening it here.
Provisions exist to allow the use of a personal router with the internet service, but in almost all cases results in having two routers in the dataflow. The main reason I can think of why people do this is twofold; first to fix broken WiFi which is not the intent of this thread, and second, to have control over the DNS used by the attached devices on the home network, and a subset of this may also involve the use of a VPN.
And so the question is, for hardcode shooters, battle royale, MMOs and any other variant where performance matters, how do you configure your internet connection, specifically for DNS. Are you satisfied with the base services provided with the ATT Internet product, or do you use an alternative DNS, Google or cloudfare or quad nine or even a VPN. If possible, empirical data, measurements and so on to back up the view would be appreciated.
