At Indiana University, a rogue DHCP server is any active DHCP server on the IU network that UITS has not approved. These appear from time to time, particularly in campus housing. Often such servers are set up unintentionally.

When a rogue DHCP server exists, many computers on a particular subnet (often a floor, a section of a building, or an entire building) suddenly have non-IU IP addresses and are unable to browse the web or access other network resources.

Note the following university policy on personal routers:

At IU Bloomington, you may operate a properly configured, FCC-approved wireless access point (WAP) as an exception to Extending the University Data Network (IT-19) and Wireless Networking (IT-20) from the University Information Policy Office (UIPO) only if your residence is listed at Wireless Networking: Temporary Exception 2 (ITE20-02). Once the campus wireless network is available in your residence, this exception will no longer apply and you will need to remove your WAP from the network.
