* from above documentation:
* Using hostaddr allows the application to avoid a host name look-up, which might be important
* in applications with time constraints. However, a host name is required for GSSAPI or SSPI
* authentication methods, as well as for verify-full SSL certificate verification.
* The following rules are used:
*
* - If host is specified without hostaddr, a host name lookup occurs.
*
* - If hostaddr is specified without host, the value for hostaddr gives the server network address.
* The connection attempt will fail if the authentication method requires a host name.
*
* - If both host and hostaddr are specified, the value for hostaddr gives the server network address.
* The value for host is ignored unless the authentication method requires it, in which case it will
* be used as the host name.
