OIT VoIP (Voice over IP) Service relies on a number of individual networks (a.k.a. "subnets"). Use this document to learn which of these VoIP subnets is associated with each building.
Note that this document only shows subnets that comprise OIT VoIP Service. Those are the subnets to which dedicated VoIP handsets (that use OIT VoIP Service) are attached, as well as some subnets to which the servers supporting OIT VoIP Service are attached. The subnets that comprise the "regular" campus data network do not appear in this document; they appear in the Princeton Network ("subnet") List.
If you have a building name, and wish to learn which OIT VoIP Service subnet(s) are associated with that building, use the Building to VoIP Network table below. Look up the building name in the first column. Read across to the second column to learn the official name of the associated subnet. (In some buildings, more than one subnet may be present. In such cases, the additional subnet(s) are listed on additional lines following the building name, and there is sometimes a comment in the third column to help you distinguish among the subnets.)
If you have an OIT VoIP Service subnet name, and wish to learn which building(s) are associated with it, use the VoIP Network to Building table (the second table below). Look up the official subnet name in the first column. Read across to the second column to learn the building(s) associated with it. (In some buildings, more than one subnet may be present. In such cases, a comment appears after the name of the building to help you distinguish among the subnets.)

That information typically includes the subnet's IP address, IP network mask ("netmask"), and the IP address of the default IP router (a.k.a. "gateway"). (The IP broadcast address isn't displayed, as for all OIT-wire networks it is identical to the subnet's IP address; we use the "all-zeros" broadcast address style.)
Most of the network names above are not links; they cannot be looked up in the Host Database because those subnets (deliberately) are not stored in the Host Database. For those networks, you can find learn the subnet's IP address, IP network mask ("netmask"), and the IP address of the default IP router (a.k.a. "gateway") by consulting voipnet Network Ranges. (Access to that document is restricted to selected OIT staff.)
