will operate as a KNXnet/IP Router:

5.2.4.2 Setting a KNXnet/IP Router via BootP or DHCP
Besides manual address allocation, two other options are available for
automatically assigning an IP address to the KNXnet/IP Router — BootP and
DHCP. This may only require the server configuration to be adjusted by the
system administrator.
BootP
The BootP “bootstrap protocol” communicates via UDP and assigns its required
data — such as IP address, subnet mask, etc. — to a fieldbus coupler/controller
during the boot process. This process requires a BootP server.
During booting, a client broadcasts a UDP request to the available network that
the BootP server responds to. It returns a packet with the required data to the
client. If the BootP server is not in the same subnet as the client, the BootP server
will require a BootP gateway.
