must have the same network-part and a unique host-part. Doug Fleenor Design recommends

users use Network 10 (address 10.X.X.X), which is intended for private (dedicated) networks

that are not connected to the internet. Another private network number is 192.168 (address

192.168.X.X). (Author's note: sACN sends DMX512 data on network address 239.255.X.X

regardless of the Node's address or mask. Thus, some aspects of a sACN network may work

even if the address and/or mask do not match.)

Subnet mask. A 32-bit IPv4 address has two parts: the network-part and the host-part. The

number of bits dedicated to each part varies by application and is historically represented by

the subnet mask. The subnet mask is a 32-bit binary number starting with a series of ones,

followed by series of zeros, such as 11111111 00000000 00000000 00000000, with ones

representing network-part bits and zeros representing host-part bits. The subnet mask is

typically written in dot-decimal form such as 255.0.0.0. Although the parts of the IPv4 address

can be split in 31 ways, the two most common in lighting are: 8 bits for network, 24 bits for host

(subnet mask 255.0.0.0) and 16 bits for each (255.255.0.0).

DHCP. The Dynamic Host Configuration Protocol is a tool used to automatically assign

addresses and subnet masks. A device that runs the DHCP is called the DHCP server. Not all

networks have a DHCP server, in which case the addresses and subnet masks are set

manually (DFD products ship with a default address and mask that work in most applications).

Note that DHCP is an app that runs on a computer, router, console, or other device on the

network; it is not a separate piece of equipment.

control network; it typically adds an unnecessary level of complexity. That said, N
