I’ve read this can be worked around by setting up a different subnet but most routers, my last one was an Asus, let you specify the DNS for static ip’s. The subnet setup is kind of daunting to me for some reason.
This would be a great feature. In my case, I want specific devices to look at PiHole for DNS. These devices don’t have the ability to set DNS on their end, they only get DNS from the router.
