Hi Francis, just a few questions out of curiosity.
- Since he had this issue on all virtual platforms: is that because something is/was off with his Windows regarding networking?
- I just tested this on my non-production HAOS which has static network settings but it keeps the DNS server that was configured before, even after restarting the instance.
I guess this is not normal behavior, right?
ps: the last command
network info
misses ha in front (in case someone bumps on this post), no?
It is complicated.
You have the dns server that supervisor uses, that is a container named hassio_dns
and you have the dns that is used inside the HA container
ha dns options --servers dns://1.1.1.1
changes the dns of the hassio_dns container, but not the dns of the HA container.

Thanks for explaining! 
Was all this because during the setup of HA the settings of the underlying OS (Windows in his case) was taken?
Always the question with DNS problems, where is the problem located ? That is why well-known DNS-servers as 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) are often a solution.
Of course it quite often DNS, but does the setup take the DNS server from the underlying OS, or not? (I guess it would work that way)
Normally from the DHCP-server
