You can enter a host name and no IP address, or you can enter an IP address and no host name. In either of these cases, the system automatically defines the value for the field that you have not entered based on the value of the field that you have entered. If you enter both a host name and an IP address, the IP address must be the correct IP address for the host name.
Enter only a host name or only an IP address, or if you enter both, ensure that the IP address is the correct address for the host name. Resubmit the task.
