WiscVPN - Static vs. Dynamic IP Addresses
This document is an overview of difference between static and dynamic WiscVPN IP addresses.
How does WiscVPN assign static versus dynamic IP addresses?
Dynamic IP service (basic WiscVPN service) provides a connection to the campus network using an IP address selected randomly from an available pool of campus IP addresses. Each time you make a connection using the WiscVPN client, you may be assigned a different campus IP address.
Static IP service will reserve a specific IP address which will always be used for your WiscVPN connection. Each time you make a connection using the WiscVPN client, you will have the same campus IP address. This can be useful when tighter security practices need to be maintained. For example, firewalls can be configured to allow only certain IP addresses through or remote access can be used from a home computer to securely access a work computer.
Should I be using a static or dynamic connection?
Most WiscVPN users will connect with a dynamic IP address. However, some high security applications such as HRS and SIS require a static IP connection. If you need to access these applications on a wireless or off-campus connection, you will need to connect with to WiscVPN with a static IP address.
Note: Static IP service is available for departmental use only.
Departments can arrange for a Static IP WiscVPN connection through the DoIT TechStore at https://techstore.doit.wisc.edu/vpn/login.asp. The static IP is activated by an automated process within 4 hours of being assigned.
