F35 here.

But looking further, it's not dnsmasq either. Yes, dnsmasq is built
with no-i18n, but as mentioned IDN2 does seem to be enabled, so I
think it's just "no i18n messages".

It seems to be the upstream dns server.

Using 8.8.8.8 explicitly makes it work for me, and that obviously
bypasses not just the local dns cache, but also the next dns server
hop.

Could be anywhere. Xfinity, Nest WiFi, or the cable router. They all
are doing their own dns thing.

Probably my cable box, since it's likely the oldest thing in the chain.
