The addressing scheme depicted in Figure 31.1 and Figure 31.2 is fairly simple: each network has a single address range. Consequently, address assignments are fairly straightforward. However, if you have multiple address ranges in the same network and you want to assign addresses from specific address ranges to specific hosts, you must screen the address assignments through the use of filters. If you do not apply a filter, the NIOS appliance assigns addresses from the highest address range to the lowest range and within each range from the highest address to the lowest address. That is, the appliance chooses the range with the highest addresses first (that is, closest to 255) and begins assigning addresses exclusively from that range, starting with the highest address and finishing with the lowest (closest to 0). When all the addresses from that range are in use, it then begins assigning addresses from the next highest range, and so on, finishing with the range with the lowest addresses. This is shown in Figure 31.3.
