Overview

  • To request a static IP address, please go to http://hippo.colorado.edu/  and select Static IP Address Application.
  • Static IP addresses on the CU Boulder campus must be assigned by OIT or other designated network administrators. A static IP address must be manually entered into a device, along with router address, subnet mask, DNS server addresses and domain information.
  • Instructions are for Mac OS 10.6, but work similarly for earlier versions of Mac OS X.
