Interpreting IP addresses on the UVM network

Explanation of what the IP address for a computer connected to the UVM network (or trying to connect) indicates

On the UVM network an IP starting with:

132.198.xxx.xxx is a valid working IP address and should have network access. (this IP indicates the computer is on the wired ethernet network or the AnyConnect VPN)

10.245.xxx.xxx is on UVM wireless network and is a valid working IP address.

10.242.xxx.xxx is a wired connection that has not been registered and will have very limited network access until the user completes the netreg process at netreg.uvm.edu

[DISCONTINUED]10.250.xxx.xxx is on the wireless CAT’S PAWS network without VPN and will have no network access unless the user runs the AnyConnect VPN client and logs in

192.168.xxx.xxx is on a router:

  • If the client is calling the Helpline from home, network troubleshooting should include power cycling this home router (unplug it from the electrical outlet, wait a few seconds, plug it back in).
  • If the caller is on campus, this indicates a rogue unauthorized router with DHCP enabled. These will be blocked if they interfere in anyway with the UVM network. Connect to UVM wireless and disconnect the router. See http://www.uvm.edu/~telcom/?Page=NewWireless/intro.html which states: “Wireless access points should only be installed by UVM Network Services. Students, staff and faculty may not allow a third-party provider to supply access on campus or install their own access points. If you suspect an unauthorized access point is interfering with your Cat’s PAWS (or UVM wireless) service, please contact Network.Services@uvm.edu.”
  • Departments and off campus remote sites need to work with network services for router authorization. See: http://www.uvm.edu/~telcom/?Page=forms/default.html under Faculty and Staff network connections for the online request form.

169.254.xxx.xxx generally indicates a network failure as it is the Windows default IP address (self-assigned IP). Check network settings for the computer in question in Control Panel.
