Scenario
You have been appointed as a Network System Administrator by the Australian government to
allocate public IP Version 4 (IPv4) addresses and build a routing table for edge routers to connect
the Australian states as shown in Figure 1.
The IPv4 is an exhaustive list of IPv4 addresses for current Internet users in the world. However,
in this scenario, you have the liberty to use the entire available unreserved public IPv4 addresses
for the Internet users in Australia.
