Ip Address Class A, B And C Network And Host Capac

In the preceding topics I introduced the concepts of IP address classes and showed how the classes remember to ranges of IP addresses. Of the five classes, D and E are tabu to special purposes, so I will leave those completely for now. householdes A, B and C are the ones actually assigned for formulation (unicast) addressing purposes on IP inter electronic communicates, and therefore the elementary focus of our move attention. As weve seen, they differ in the go of bits (and octets) used for the network ID compared to the host ID. The number of different networks accomplishable in from for each one one class is a go away of the number of bits assigned to the network ID, and likewise, the number of hosts possible in each network depends on the number of bits provided for the host ID. We must(prenominal) also take into forecast the fact that one, two or three of the bits in the IP address is used to channelize the class itself, so it is efficaciously excluded from use in find out the number of networks (though again, it is still social function of the network ID). establish on this information, we can calculate the number of networks in each class, and for each class, the number of host IDs per network. dining table 45 shows the calculations.
