What factors need to be considered when selecting an IPv4 address?

What will be an ideal response?

Several factors need to be considered when selecting IPv4 addresses. For example, organizations should choose a class address that reflects not only the current size of the enterprise, but one that will also accommodate future expansion of the network. Each intranet within the organization must be given a unique, accurately documented network address. The larger the enterprise, the more important full and accurate documentation becomes. Within a specific LAN or intranet, host addressing should be well thought out and planned. Each host within a LAN must have a unique address. Network administrators should be careful not to assign host addresses that are restricted, such as all zeros or all ones. Using particular ranges of host addresses that identify specific types of devices can also be beneficial; for example, having servers fall within one range of host address values and routers within a different range.
