ISERink (A Cyber Playground)

In past years, physical access to hardware and operating systems for the students to practice with has been provided two ways.  In the early years, computer hardware was donated to the program from corporations.  The systems were refurbished and reshipped to the high schools to setup.  This was not a scalable process.  Therefore, in more recent years, the high schools were told to ask for donations of old equipment from companies geographically close to them.  While this reduced the refurbishing and shipping requirements on the outreach program staff, it created inequities in what the students had at each school.

To solve this problem, we have created a “playground” called ISERink that is available to the students enrolled in the IT-Club in the fall of the year.  This allows uniform access to equipment.  Each IT-Club is given remote access to a network in which they can experiment; building different operating systems and installing different network services.  The high school students spend the entire year remotely working in their assigned network space.

Network Information

One of the unique features of ISERink is the use of the public IP address space for each group using ISERink.  For IT-Adventures each school has been assigned a public IP address that they can connect the systems with build inside ISERink.  The IP assignment is provided at this link: ISERink IP Ranges

Default Gateway & DNS

Your default route (gateway) is the IP sitting at .254 of your range. The netmask is
The DNS server is located at – for example, school1′s gateway is If your network is set up correctly, you should always be able to ping your default route and get a response.

Proxy Server

Inside ISERink, you will not have access to the internet. Instead, you must use our proxy server, located at:, port 3128 
Package Managers
To con gure yum, apt, wget and other software to use a proxy in Linux/UNIX:
export http_proxy=""
export https_proxy=$http_proxy
export ftp_proxy=$http_proxy
If you fi nd that apt-get is still not working, edit the file /etc/apt/apt.conf (or create it if it does not exist) and add or edit the following lines:
Acquire::http::Proxy "";
Acquire::ftp::Proxy "";


ISERink is based on the ISEAGE testbed and is similar in configuration to the competition environment used for the Cyber Defense Competition that is part of IT-Olympics.

The Internet-Scale Event and Attack Generation Environment (ISEAGE) network testbed housed at Iowa State University, and its portable counterpart ISECube, are premier facilities dedicated to creating a virtual internet for the purpose of conducting research, system testing, critical infrastructure modeling, training and education, and outreach.

Both the ISEAGE and ISECube testbeds create a routable internet with real computers and networking hardware, not just programming software. Unlike conventional testbeds where each router is represented by either a real router or a software router running on a computer, ISEAGE can have up to 100 routers per board and these routers can be configured to create arbitrary topologies. It is a controlled environment where real world attacks can be played out against different configurations of equipment, as well as different network topologies.

ISEAGE is a world class research and education facility where more than 30 faculty members and over 50 graduate students use the flexibility of the ISEAGE’s current 64-node reconfigurable environment on projects related to cyber security and physical infrastructure protection. To date, ISEAGE has been used primarily to test network security and for cyber security modeling, as well as to support cyber defense simulations and cyber security preparedness training.
