Network Segments

A "Network Segment" is a portion of a network that is bordered by two router
interfaces as shown in Figure A-8.
Each network segment must either be on a different network or a different
subnet. For example, if you have a single IP address available, you can change
the default mask from 255.255.255.0 to 255.255.255.192. The resulting calcula-
tion yields four subnets:
• 192.168.100.0
• 192.168.100.64
• 192.168.100.128
• 192.168.100.192
