  Bug#27427: resolveip fails on hostnames with a leading digit
  
  "resolveip" program produces incorrect result if given a hostname
  starting with a digit.  Someone seems to have thought that names 
  can not have digits at the beginning.
  
  Instead, use the resolver library to work out the rules of hostnames, 
  as it will undoubtedly be better at it than we are.

    Hostnames may begin with a number.  We should use the resolver
    library to make such decisions.
