Understanding IP Addressing

B-5

Note: If you receive an IP address from an ISP, there must be a mask associated with that IP address. By using the IP address with the mask you can discover exactly how many IP host addresses you actually have.

To configure subnets properly, you must also be able to convert between binary notation and decimal notation.

Example: Using subnets on a Class C IP internet

Suppose that your organization has a total of 25 IP hosts situated on three different floors of your office building, and that you are in charge of designing the network that will connect them. You obtain a Class C network number, 199.14.17.0, since you expect that your organization will always have fewer than 254 IP hosts. All your IP hosts will use IP addresses of the form 199.14.17.x, where x represents the eight bits that can be used for subnet numbers and individual host numbers.

How many of the final eight bits of the IP address should you reserve for hosts, and how many should you use for subnet numbers? The answer depends on how many subnets you expect to need, and how many hosts you expect to put on each subnet. All 25 of your hosts could certainly coexist on one network that does not use subnetting. However, you are fortunate enough to have two IP routers on hand, so you decide to lower traffic levels and simplify troubleshooting by setting up three subnets, one for each floor. The following table lists how many subnets and how many hosts you may have for a Class C network, depending on how many bits you allocate to the subnet numbers.
