Overview

OIT assists customers with name and address management by providing Static IP addresses and Dynamic DNS. Learn more about getting a Static IP address below.

About Static IP Address Assignments

Static IP addresses are needed for devices such as printers or servers that need the same IP address all the time.  DHCP (Dynamic Host Configuration Protocol) is the campus standard and should be used for all devices that do not need a static IP address. A Static IP address must be assigned by OIT and it must be manually configured in the device, it is not configured automatically. Static IP addresses are not assigned for UCB Wireless.
