Table 4: KNX Multicast Address
NOTE: The Multicast IP address 224.0.23.12 is the defined address for the KNXnet/IP from the KNX
Association in conjunction with the IANA. This address should stay as defined and only changed if it
becomes necessary due to the existing network.
By commissioning, it should be regarded that all KNX IP devices which should communicate with one
another via IP must use the same IP routing multicast address.
