Its nothing major and feel free to ignore this:
I have a simple idea for the list of machines page. I happen to browse the page often just to get the IP of a machine. There is no easy way to copy the IP as I cant select the IP text itself. I end up going into the machines detail page where I copy the IP from the URL bar (the IP entries on the page itself again are not selectable). Maybe consider copying the IP to the clipboard onClick() on the IP text or add a little clipboard icon next to the IP.
I like your service and that would make my life easier
