  Not sure what you're after there.

  Windows allows underscores in the hostname.  Linux also allows
underscores in the hostname.  There is no rule that says your hostname
has to be exposed to the Internet.  Windows 2000 and later warn you
that things will break if you use underscores, and include options to
reject them entirely.

  Microsoft does use underscores to prefix the DNS labels for SRV
records, but since *the RFC says to do that*, I think that's a good
thing.

  (I detest FUD, even if it's aimed at a target I also dislike.)
