  Numerical IPv4 addresses have large overlap with hostnames.

  As I've said repeatedly, it's just not possible to do this right, all of the time.  *NOT* doing it badly is better than doing it badly.

  Please look at the code and see how "simple" this is.  It's not.

  $ was already used.  @ is used by other languages for different things.  & is a compromise.
