Additional Items

Every IP connection has additional information that is associated with it's operation.

The subnet mask is an another 32-bit number that identifies what network the IP address belongs. Computers with IP addresses on the same subnet can talk to each other natively. IP addresses with different subnet masks must communicate through a translating device such as a router to exchange information. A common example of a subnet mask is;

255.255.255.0

The subnet mask for all IP addresses in use at Logan Hall is 255.255.252.0 and 255.255.255.128 for all of the addresses in Fiji House.

Default gateway is the IP address of another computer that acts as the exit ramp for all traffic leaving the network. The most common use for a default gateway is to allow computers on the network to access the Internet. Corporate environments use a 'proxy server' as a default gateway to filter and protect outgoing network traffic.

The default gateway address for Logan Hall is 130.91.236.1 and 165.123.54.1 for Fiji House.

Every computer with an IP address needs the IP address of a DNS server to resolve names of web-sites on the Internet. Without a proper DNS server and the correct subnet mask, a computer will not be able to access the Internet. All computers on-campus use the same DNS server addresses. Three DNS server addresses are provided for load-balancing and redundancy. These addresses only work while on-campus and not off-campus.

The Penn DNS servers are 128.91.2.13, 128.91.254.1, and 128.91.254.4.

Unix-like OS

In many Unix-like operating systems (for example, Ubuntu, RHEL, macOS, BSD), a shared system administration utility known as ifconfig is available to configure, control, and query TCP/IP network interface parameters from a command-line interface (CLI). Typically, ifconfig can only be used under a superuser account in your terminal.

To get your IP address from ifconfig, enter the following:
