ILGs are connected to the MIT network in two basic ways. The FSILGs that are considered "on campus" are those ILGS that are in close proximity to other MIT buildings. These houses are connected directly to the MIT network just like any of the residence halls. There is a direct fiber connection between the house and the MIT backbone routers. Each of these houses have a fiber interface device and a router installed and maintained by IS&T.

The FSILGs that are considered "off campus" are those ILGS that are not in close proximity to other MIT buildings. The physical connection to these houses is provided by Verizon. IS&T pays for the 10Mbps FTTP (fiber to the premesis) service for each off campus FSILG. Verizon's VLAN makes the connection to MIT appear seemless and despite the physical differences, the virtual representation of the network is very much the same as for on campus FSILGS. The equipment inside an off campus ILG is installed and maintained by both MIT and Verizon. The fiber interface box (9145) is branded and maintained by Verizon while the router (Cisco 4000) is maintained by MIT.

The differences in these houses on a support level can be seen by viewing the Getting help section of these ILGs pages. Off campus ILGs have one additional party that can be involved in the troubleshooting process. This makes following the correct escalation path vital to a quick resolution.

Each FSILG is allotted a class B network. The IP address of the MIT router, or house gateway is 18.sub.0.1 where sub is the three digit subnet value for your house. All of the IP addresses within your network are in the 18.sub.0.0 network. ILG network contacts can use the MIT Moira database to add hostnames and static IP address assignments to their network and the DHCP registrations should be handled by the MIT DHCP servers.
