      Now current
        practice is that people use the gethostbyname() call to do DNS
        resolution and so they end up being unable to make use of DNS
        properly. But that is a problem with the 40 year old legacy API
        which can be changed or circumvented entirely
      

      RFC6763 is what
        the application layer should use.
    
    Uh, no.  It's hopelessly fragile and completely inadequate.
