Description:
 def get_host(self, retry_count=3):
 """ The function for retrieving host information for an IP address. Args: retry_count (:obj:`int`):
 The number of times to retry in case socket errors, timeouts, connection resets, etc. are encountered. Defaults to 3. Returns: namedtuple: :hostname (str):
 The hostname returned mapped to the given IP address. :aliaslist (list):
 Alternate names for the given IP address. :ipaddrlist (list):
 IPv4/v6 addresses mapped to the same hostname. Raises: HostLookupError: The host lookup failed. """
