Istation being used in the classroom.

Network Administrators

Istation employs a proprietary communication protocol designed to minimize bandwidth usage when simultaneously run by multiple students in a school. Internal firewalls and/or content filters must be configured to allow outbound access to our servers:

  • TCP ports 12500 - 12509
  • IP address range: - ( - (,
  • Some options may require additional IP addresses

Local Firewall Information

When a software firewall is active on a computer, the firewall must be configured to allow Istation to accept connections from the local network. On Windows, this configuration occurs automatically during installation. For information specific to your OS, please review the detailed installation instructions for Windows (607KB) or for Mac (566KB). Additional information may also be obtained by calling Istation support at 1-214-237-9300 or 972-643-3440 (option 2).

Firewall Configuration Test

Test your firewall configuration now using the Firewall Configuration Test utility.

E-mail Access

If your district uses an e-mail filtering software or program, please add the domain to your white list to allow inbound access via e-mail. This is our main method of communication with campus teachers and administrators.
