Hope you guys are doing well but I do have one question. My current router in my home is a XR500 which has 3rd spot for a DNS and btw the DNS you see is from Adguard in the picutre but I'm probably going to change it soon anyways. My main question is what DNS should I put in the third spot? Is it worth makng another NextDNS configuration and setting the 3rd spot for the DNS? I feel like that would be a bad idea anyways if something were do happen to NextDNS.
