Let everything ultimately use their DNS as primary... it is served via their v6 network to the Askey, which will forward the results over it's local v4 LAN or V6 segment (you can do v6 passthrough via a personal router if you are using one... not the greatest, but it kinda sorta works).  If you poke around the GUI you will see it reference the v6 gateway and DNS in play upstream from the Askey.  May have to be in  Expert view to see it... forget the details.

Queries to an external v4 DNS will have to go through their funky 464xlat/CGN tunnel crud to get there and back.  Think of it like using a firewalled VPN for the queries, versus a more direct query.

Depending on your local setup, it could get a bit funky. 

Note that with the Askey, you can change the private address space if you want, so if you are doing a double-nat set up (personal router in NAT mode not as an access point), you can set them up with more unique IP ranges.

The Askey forwards it over it's v4 private LAN subnet, and if you are using your own router in native mode, that will have to forward again to it's private LAN subnet.  This will inject a little extra lag, but should be considerably less than what you are getting trying to force google/cloudflare/others as the primary DNS.  For the clients you configure manually, would want to point to the router(s) first, then any external provider you want to hit.  Por ejemplo:

10.10.x.x (personal router in NAT mode)

192.168.x.x (TMO Askey)

(Put the local gateway with better response time first, then you can list external providers as you see fit)

8.8.8.8

1.1.1.1

 

Forget where I got referred to it, may have been speedguide.net.  But there is a DNS Benchmark tool you can download for free that you can use to test responsiveness of your DNS setup.  May want to Google for it, just make sure it is coming coming from reputable source and all.

EDIT:  found it…

Hoping they start shipping the new 5g hardware soon so we can get a feel for how they hold up.  The bands have been available in our market for quite a while now... but we are all still on the Askey LTE boxes.
