Network Addressing
Subnet Addresses
INTERFACE_NAME[3]=”lan1:1”
IP_ADDRESS[3]=”192.6.12.98”
SUBNET_MASK[3]=”255.255.255.224”
Host D:
INTERFACE_NAME[0]=”lan0”
IP_ADDRESS[0]=”192.6.12.35”
SUBNET_MASK[0]=”255.255.255.224”
INTERFACE_NAME[1]=”lan1”
IP_ADDRESS[1]=”192.6.20.1”
SUBNET_MASK[1]= 255.255.255.0
In addition, every other host on each subnetwork would require the
subnet mask 255.255.255.224 in their netconf file entries.
Example of Network Map with Fixed-Length Subnets
This sample network combines networks, subnets with a fixed-length
mask, and clusters previously described and illustrated in this chapter
along with a sample worksheet that provides configuration information
necessary to attach these systems to the networks.
