5.Determine the host addresses

Finally, combine your subnet numbers with your host numbers to determine the actual IP addresses you may use for your 25 hosts. The first three bytes of the address will always be 199.14.17, as assigned to you by InterNIC. The final byte will be the sum of the subnet number and the host number. The following table shows the ranges of IP addresses you can choose from when you configure each host.

Example: Working with a Class C subnet

Suppose that your organization has a site with only 10 hosts, and no plans to add any new hosts. You don’t need a full Class C address for this site. Many ISPs offer Internet access with only a portion of a full Internet address.

For example, you may obtain the Class C address 199.14.17.48, with the mask 255.255.255.240. From the previous example, you can see that this gives you 14 host addresses to distribute to the hosts at your site. In effect, your existing network of 10 hosts is a subnet of the ISP’s network. Since the Class C address has already been reduced to subnets, you cannot further subnet your network without the risk of creating network routing problems (since you
