Hi musl:

I found the implementaion of name_from_hosts function is case sensitive, and it should be case insensitive according the rfc<https://tools.ietf.org/html/rfc4343>.


Best Regards,

Thanks for reminding me of this -- I think I was aware at one point,
but had forgotten and even had to re-check. This should be fixed when
we add IDN support, since case normalization before making the query
is necessary, so I think maybe we should go ahead and try to finish
IDN support sooner rather than later.
