Campus Data Network ("Subnet") List

The Princeton University campus data network ("CDN") is composed of many individual networks (a.k.a. "subnets"). Use this document to learn which of these subnets is associated with each building.

If you have a building name, and wish to learn which campus data network (CDN) subnet(s) are associated with that building, use the Building to 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 a campus data network subnet name, and wish to learn which building(s) are associated with it, use the 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.)

There are a couple of technical notes at the bottom of this document.

Notes

• The network named pu-dormnet-bb is informally called Dormnet.

• Only Campus Data Network ("CDN") subnets appear in this document. Subnets which are part of the Princeton Private Network ("PPN"), and those which are part of OIT VoIP Service do not appear in this document.

• Networks and locations relevant to end-users are listed. Some other networks (e.g., those used to support the infrastructure) and locations (e.g. OIT's data centers) are not listed above.

• If you click on the name of a subnet, some technical information about that subnet will be displayed. (The ability to perform this lookup is restricted to those computers that are members of the Princeton.EDU DNS domain.)

  That information typically includes the subnet's IP address, IP network mask ("netmask"), the IP address of the default IP router (a.k.a. "gateway"), and the IP address of one or more Domain Name Servers. (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.)

  Another way to obtain the network mask, default IP router, and broadcast address appropriate for a specific IP address is to consult Default IP Routers, Network Masks, and Broadcast Addresses.
