Using <literal>hostaddr</> instead of host allows the application to avoid a host
name look-up, which may be important in applications with time
constraints. However, Kerberos authentication requires the host
- name. The following therefore applies. If host is specified without

<literal>hostaddr</>, a host name lookup is forced. If <literal>hostaddr</> is specified without
host, the value for <literal>hostaddr</> gives the remote address; if Kerberos is
used, this causes a reverse name query. If both host and <literal>hostaddr</> are
