By looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.

The key to a successful hierarchical network structure is proper IP address management. If addresses are assigned appropriately, it is possible to summarize routing information. TIP Each area used by OSPF or integrated IS-IS should have a contiguous set of network or subnet numbers assigned to it. The area border routers should summarize that set of addresses with an address mask. Summarization provides substantial benefits for your network.
