I'm not aware of any off the top of my head... A quick look in the api explorer didn't show anything obvious either.. If I had to do this, I would use the "command" object and then use the "hostname" command to get the hostname, or use ipconfig or ifconfig depending on the OS to get the IP info.
See Joerg's great post here to learn more about running local commands:
