Configure Digi devices
DHCP server settings
The DHCP server feature can be enabled in a Digi device to allow other devices or hosts
on this network to be assigned dynamic IP addresses. This DHCP server supports a single
subnetwork scope.
For the DHCP server to operate, the Digi device must be configured to use a static IP
address. For information on how to configure static IP settings, see "IP settings" on page
76.
The Digi Connect WAN IA has different factory defaults for DHCP server. The DHCP
server is disabled, and DHCP Client enabled.
For information on how to manage the DHCP server, see "Manage DHCP server
operation" on page 190.
DHCP terminology
Some key DHCP terms involved in configuring a DHCP server include:
scope
A scope is the full consecutive range of possible IP addresses for a network. A scope
typically defines a single physical subnet on your network, to which DHCP services are
offered. A scope is the primary way for the DHCP server to manage distribution and
assignment of IP addresses and related configuration parameters to its clients on the
network.
exclusion range
An exclusion range is a limited sequence of IP addresses within a scope, excluded from
DHCP service offerings. Exclusion ranges assure that any addresses in these ranges are
not offered by the server to DHCP clients on your network.
address pool
After the scope is defined and exclusion ranges are applied, the remaining addresses
form the available address pool within the scope. The addresses in this pool are
available for dynamic assignment by the server to DHCP clients on your network.
