Business Case Scenarios Scenario 1-1: Calculating IPv4 Subnets As the enterprise administrator, you have assigned Arthur the network address 172.16.85.0/25 for the branch office network that he is constructing. Arthur calculates that this gives him 126 (27) IP addresses, which is enough for his network, but he has determined that he needs six subnets with at least 10 hosts on each one. How can Arthur subnet the address he has been given to satisfy his needs? Which IP addresses and subnet masks will the computers on his branch office network use?

Arthur can subnet the address he has been given by using three host bits to give him eight subnets with up to 16 hosts on each one. The computers will use a subnet mask of 255.255.255.240 and IP address ranges as follows: 172.16.85.1-172.16.85.14 172.16.85.17-172.16.85.30 172.16.85.33-172.16.85.46 172.16.85.49-172.16.85.62 172.16.85.65-172.16.85.78 172.16.85.81-172.16.85.94 172.16.85.97-172.16.85.110 172.16.85.113-172.16.85.126 172.16.85.129-172.16.85.142 172.16.85.145-172.16.85.158 172.16.85.161-172.16.85.174 172.16.85.177-172.16.85.190 172.16.85.193-172.16.85.206 172.16.85.209-172.16.85.222 172.16.85.225-172.16.85.238 172.16.85.241-172.16.85.254

Scenario 1-2: Expanding the Network You are an administrator with a network address of 172.16.0.0/24. Currently, you are responsible for 40 sites; each site has between 20 and 100 users. However, soon, you will be creating corporate and regional offices that need to hold 500 users. Each of the sites are connected through NAT devices. Many users will be using multiple computer devices and you will be hosting many servers. You want to make sure you do not run out of addresses any time soon. So, you decide to implement IPv6. What will you need to do so that you can start using IPv6 with IPv4 until the transition is complete?

You will need to upgrade or replace much of your network equipment, such as routers and switches that will support IPv6. Until you get to that point, you will have to implement one of the IPv4 to IPv6 transition technologies such as 6to4, ISATAP, and Teredo. However, because you want to run IPv4 and IPv6 while you transition, you can use the 6to4 transition mechanism.
