About Static IP Addresses

Static IP addresses are IP addresses that are permanently assigned to a device by ITS (Information Technology Services). While automatically assigned addresses (i.e. DHCP) may change over time, statically-assigned addresses will remain the same. This is required for servers and often desirable for printers, projectors, etc.
