https works also without names it is just less common.
Example:
https://1.1.1.1/

but event that is not needed in this specific case since Kenji mentioned
that they plan to initially ship a hardcoded list that maps resolver IPs
to DoH URIs. From the thread on the dns-privacy list:

> Until there is a better discovery story, we could have a list of
