How do I test ssh to multiple hosts and log success/failure to an output file?

I'm using sshpass to check connectivity to devices with a common user/password combo.
sshpass -p mypassword ssh -q username@ipaddress
I want to run a loop over a file with multiple ip addresses, outputting the results of ssh to an output file. Is it possible? Also, for devices that are not reachable for any particular reason, there seems to be an issue of timeout delay (20+ seconds). Is there a way to break out of an ssh attempt after say 5 seconds and move on to the next addess?
shell-script ssh sshpass

You can useforto set up a loop in script, and look at optionConnectTimeoutinssh_config: "Specifies the timeout (in seconds) used when connecting to the SSH server, instead of using the default system TCP timeout. This value is used only when the target is down or really unreachable, not when it refuses the connection."
