code: def get_meta(self):
          
          # get the normalized IP if we don't already have it
          if self._meta is None:
              external_ip = get_external_ip()
              if external_ip:
                  self._meta = get_meta(self.config, external_ip)
              else:
                  raise Exception("Unable to get public IP")
              if 'custom_meta' in self.config:
                  self._meta['custom_meta'] = self.config['custom_meta']
  
          return self._meta
docs: we only want to get the meta information (our normalized IP) once,
          so we are going to do lazy instantiation to improve performance
