Hello
In my hardware system I am using an ISRC1111 using NO DNS preferences connected to an FPR using no DNS preferences which connects to an SG350XG which has DHCP Servers and uses [Pi-Hole] VM as it's local dns and dns server, which blocks ads so on so forth.
I was curious if Cisco, or on any of these devices, uses a format or solution that could take place from Pi-Hole so that I could not have to use a VM for this sort of function.
