DHCP
DHCP is a further development of BootP. Whereas BootP assigns IP addresses
from an address table to the clients and cannot accept further clients when all
addresses from the table have been assigned, DHCP offers the benefit of a three
assignment techniques, including possible dynamic assignment.
5.2.4.3 DHCP Assignment Techniques
• Static assignment
This assignment corresponds to the assignment by BootP. Each client
always receives the same IP address.
• Automatic assignment
The server receives a list of IP addresses (defined by addressing space and
subnet masks) from which it assigns a free address to a client. The client
receives this address for an unlimited time.
• Dynamic assignment
Similar to automatic assignment, but after a defined time, the client loses its
IP address.
Figure 37: MAC address on the controller
In all previously mentioned cases, the specification of the MAC address to enable
a globally unique assignment of a network device is mandatory. The MAC
address is shown on the address label on one side of the KNXnet/IP Controller.
You will also find the MAC address on the WBM pages of your controller.
A routing multicast address representing an IP address must also be defined (see
Section “Manual Setting of the KNXnet/IP Router”).
