DNS won’t reduce lag directly, but it can make your connection feel snappier. I use Quad9 (9.9.9.9) for my Xbox—it’s got built-in security and decent speeds.
For testing, try pinging different DNS servers from your PC to see which has the lowest response time. That’ll give you a better idea of what’ll work for your xbox dns settings.
