When the SSH connection fails due iTest executes a Global Event called OnTerminalOpenConnectionFail. You can see this in the test report when you execute your test case and find a missing ip address.
You have the ability to modify this event. While editing your test case, there is a tab (look at the bottom of the editor view) that is labeled "Global Events". If you click on that tab, the editor will change to show you all the global events for that test case. Above the list on the left, you'll see a search box. Type "OnTerminalOpenConnectionFail" in that box and you find the global event.
You can change the steps by unchecking the inherit checkbox. If you notice, one of the steps is "AbortExecution". This is the step that is ending your test case at the point of the missing ip address. You can remove this step and execution will continue.
Depending on what you want to do after the open call, you may need to set a variable and add an "if" statement to your for/foreach loop. If the device doesn't open, you don't want to try to use it!
