- Exit 1 if "add", "change", or "delete" operation fails.

PR:		bin/12489

- Use inet_ntoa(3) where it should have been used.  This
  part of code simply wasn't converted to the "new" style
  after the routename() function was converted from the
  protocol-generic version to protocol-specific version
  in CSRG revision 5.6.
