After successful authentication for the identity service, you can specify the host name or IP address for the target system. If the DNS name is stored for the target, you must specify the fully-qualified domain name. If the IP address is stored for the target, you must specify the IP address. There is no automatic translation between IP addresses and host names.
If the target is found and logging on requires multi-factor authentication, you might be prompted to select a mechanism or respond to a challenge.
