Internet Protocol Ver. 4 is the most popular protocol but is dated as there is new version called IPv6, which was finalized in 1998 and solves issues in previous versions, additionally it stores a 128-bit address as opposed to the previous 32-bit, making for massive improvement on IP address quantities. IPv4 could have approximately 4 billion addresses with IPv6 has something in the ball park of 3.4×1038 . IPv4 has three main classes, today we’ll focus on two specifically class B, and Class C. To Connect a Class B (128-191)[10], and a Class C(192-223)[110] network we will need hardware in the form of multiple computers, a switch, and a router.

First and foremost an outline needs to be made naming each address on both the B and C network. In this case the B Class network went with three IP addresses one for each computer on the network:


B Class Subnet Mask:


And the C Class network addresses for each user are as follows:


C Class Subnet Mask:


the first three octets denote the network address and the final octet denotes the unique host number as noted on the lab hand-out

To reconfigure the default IP address from the KSU POLYTECHNIC Campus’s network, you need to navigate to the computers Control panel, then continue to network settings, and then remove any previous IPv4 TCP/IP addresses on the machine, you can do so by clicking the “change network adapter settings” button.

once all the IP addresses are changed and the computers are plugged from the PC to the switch and then to the router. Using a program called “Hyperterminal” an administrator will add the the following commands

  • N – No, we will be manually configuring the router
  • EN
  • Config T
  • INT e0
  • IP add (add the IP address and subnet mask)
  • no shutdown
  • exit
  • router rip (enabling routing protocol)
  • network (CLASS C)
  • network (CLASS B)
  • exit
  • exit
  • copy run start (saves config)
  • show run(show running config)

Testing the two networks by pinging an IP on the B side from the C side should yield a ping back and thus completing the network.
