If you're getting the error message, "Your computer is registered in the networking database, node state is good,but you have a non-routable ip address.", this usually means there was a glitch during the registration process. This most often happens when you start (but do not complete) the registration process on one network (e.g., Stanford Residences) and resume the process on a different network (e.g., Stanford). Either way if you're seeing this message someone with the right access needs to resolve it manually. To expedite the process you can locate and provide the hardware address (also known as a MAC address) for the device (Here are instructions on how to find it) and Submit a Request for assistance.
Support staff will notify you when the issue is resolved or ask for additional information if necessary.
