Configuring IP addresses

The IP address mode determines how IP addresses are assigned. There are two modes for assigning
IP addresses:
Dynamic: Allows IP addresses to be automatically assigned using the Dynamic Host
n
Configuration Protocol (DHCP) and/or Auto Private IP Addressing (APIP or AUTO IP).
Static: Requires you to assign a static IP address using any available configuration interface.
n
By default, ConnectPort LTS devices are configured to dynamically assign addresses using DHCP.
Even if a DHCP server is available for dynamically assigning IP addresses, static addresses may work
better for your network configuration. Once set, static IP addresses do not change and other network
devices can always find the device by its IP address. With dynamic settings, the DHCP server can
change the IP address frequently or infrequently depending on how your network administrator has
configured the network.
When the IP address changes, network devices configured to talk to the ConnectPort LTS device can
no longer access the device. In this case, you must locate the Digi device using the Digi Device
Discovery utility and reconfigure the other network devices that need to communicate with the
ConnectPort LTS device.
The following table summarizes methods for assigning an IP address.

Use APIPA to automatically assign an IP address to the Digi device from a reserved
Auto Private
pool of standard Auto-IP addresses on a DHCP server. If the DHCP server is

Utility, the web interface, LCD, or the command-line interface. Once set, these
settings do not change. The IP address and subnet mask are mandatory. Additional
settings may be needed for some functions. Contact your network administrator for
the required values.
