referring to the subnet mask. In the subnet you also have four octets containing either
the number 255 or the number 0. This denotes which octet in the IP address is part of
the network number. For example:
 If the IP address is 10.15.20.13 and the subnet is 255.0.0.0 Then this device is on
the 10 network and it is device 15.20.13
 If the IP address is 10.15.20.13 and the subnet is 255.255.0.0 Then that device is
on the 10.15 network and it is device 20.13
 If the IP address is 10.15.20.13 and the subnet is 255.255.255.0 Then that device is
on the 10.15.20 network and it is device 13
 If the IP address is 192.168.1.100 and the subnet is 255.255.255.0 Then that
device is on the 192.168.1 network and it is device 100.
For devices to communicate with each other they must all have the same network
number but have unique device numbers. On a DigiLinX network, devices have a
subnet mask of 255.0.0.0 and an IP address of 10.x.x.x. This means that all devices on
a DigiLinX network must have an IP address starting with 10 and the remaining
numbers must be unique. Table 2-1 shows three devices and whether they can
communicate with each other.
This explanation of TCP/IP explains key networking concepts of DigiLinX. The next
section explains how a DigiLinX network is assembled.
Building a DigiLinX IP Network
By default, DigiLinX automatically assigns IP addresses using a NetStreams AutoIP
process (not to be confused with Dynamic Host Configuration Protocol - DHCP). This
allows DigiLinX to function as a standalone system. Figure 2-20 is a simple DigiLinX
network with sample IP addresses:

10.15.1.110 255.0.0.0 10.16.5.25 255.0.0.0 Yes they can talk.
10.15.1.110 255.255.0.0 10.16.5.25 255.255.0.0 No, the subnet makes the first 2
octets the network number and in
this example the first two octets
are not the same so they are not
part of the same system.
10.15.1.110 255.255.255.0 192.168.1.110 255.255.255.0 No, the network numbers are not
the same. The subnet requires
that the first three octets be the
same. These are clearly not.
