@pseudonym @fdroid interesting problem. DNS serving is IP based (i.e. site/network configured; DHCP), so I have trouble imagining how a "for your domain" DNS service would work. A VPN provides a newer DNS server address, but that requires it to run constantly. I have set up ChromeOS Flex with a VPN and it disconnects when sleeping and needs manual reconnecting. Therefore: possible, but annoying. Reliable and automatic requires software mods of your host local DNS cache (like dnsmasq) cli flags.
