No, if IPv6 is disabled, anything IPv6 is skipped or ignored in
evaluation of what to do.

Probably, yes. In the past, it had to be a configure option because
different code was needed for DNS resolution for IPv6 and IPv4, but we
unified it since, and now it could be a runtime option.

Perhaps something for a low-priority TODO list, or for some new
contributor to cut their teeth on. :)
