I think they might be talking about manual configuration. Some systems let you configure DNS separately from IP configuration. (So you could set up custom DNS while using DHCP) With some you’d have to set static IP as well, which might not be convenient but also possible.
No I know in don’t need to use Mullvad to change my local machines DNS, but I’m using it anyway so may as well.
But I am curious about I could get other networked devices to use DNS on my local machine. Do you mean set up a hotspot and point everything to that?
