This is sort of a double (or triple) post but greatly simplified,

I need a router with WiFi 6 support that has the ability to add CNAME records to its DNS server. I assume (based completely on wishful thinking) that a router natively running OpenWrt or DD-WRT has a way for users to configure its DNS server. Am I dreaming? I know that the Merlin firmware for ASUS routers has this support - I'm using it right now - but I would rather be using a router running native firmware. I'm using my ASUS router (RT-AX86U) and the Merlin firmware on;y because of the support for DNS server customization. Otherwise, bit the router and firmware are overkill for my needs.

The recent more extensive posting is here.
 
Keep your AX86U and flash the Asus firmware. Get a Raspberry Pi (Pi 3b+ works well) and set up Pi-Hole. It has the ability to use CNAME. You can also use an old PC running Linux of some sort. Then set the Asus router to use the Pi-Hole (LAN-DHCP Server-DNS Server 1). Less than a $50 investment.
 
Adding another device to my configuration isn't part of my simplification scheme. And I don't speak Linux. Setting up a separate DNS server on a Raspberry Pi is probably more than I want to handle right now (regardless of how straightforward it may seen to you).

I do have a couple NAS devices - one Synology & one QNAP - that can run a DNS server so I guess I could look into that ... although I would have to give it a static IP address.

A bonehead question: I'm currently pointing my ASUS router's DNS setting to 1.1.1.1 and 9.9.9.9. Are those used round-robin or is 9.9.9.9 a backup? If I have an external DNS server living on 192.168.50.2 (pointing to 1.1.1.1 and 9.9.9.9) and had my router pointing to 192.169.50.2 and 9.9.9.9 would the router use 192.168.50.2 whenever it was available or would half the unchached requests go to 9999?

A bonehead question #2: Are IPv4 and IPv6 completely separate in the AX86U, or would me external DNS server have implement both IPv4 and IPv6 DNS support? (I know the two functions are specified separately in Merlin, but I don't know about the ASUS native support.)

Not good to mix DNS upstream resolvers. 1.1.1.1 is Cloudflare and not filtered. 9.9.9.9 is Quad9 and is filtered.
Better to use 1.1.1.2 and 1.0.0.2 Cloudflare Security or 9.9.9.9 and 149.112.112.112 which is Quad9

Neither setup is roundrobin unless you have DoT set up with Stubby or use the Asus built in DoT.

Setting up a Raspberry Pi is easy. And so is Pi-Hole. Plenty of how to's on the web.
