IP Address Distribution (DHCP)
IP Address Distribution (DHCP)The Adit’s DHCP server makes it possible to easily add computers that are configured as DHCP clients
to the network. It provides a mechanism for allocating IP addresses to these hosts and for delivering
network configuration parameters to them.
The DHCP-based autoconfiguration feature provides a method of updating the Adit’s firmware and
configuration automatically. This is accomplished by querying a DHCP server in the boot sequence,
then using the data provided to download firmware and configuration files, and then rebooting if there
are changes that need to take effect.
A client (host) sends out a broadcast message on the LAN requesting an IP address for itself. The DHCP
server then checks its list of available addresses and leases a local IP address to the host for a specific
period of time and simultaneously designates this IP address as “taken”. At this point the host is
configured with an IP address for the duration of the lease.
The host can choose to renew an expiring lease or let it expire. If it chooses to renew a lease, it will also
receive current information about network services, as it did with the original lease, allowing it to update
its network configurations to reflect any changes that may have occurred since it first connected to the
network. If the host wishes to terminate a lease before its expiration, it can send a release message to
the DHCP server, which will then make the IP address available for use by others.
Summary of Services
To view a summary of the services currently being provided by the DHCP server, select Advanced/ IP
Address Distribution.
NOTE: If a device is listed as Disabled in the Status column, DHCP services are not being
provided to hosts connected to the network through that device. This means that the Adit will
not assign IP addresses to these computers. This may be of some use when working with
static IP addresses only.
