IP-AddressAt the early stage of internet development, those scheme become something bigger than needed. The IP creator realized that some networks only have thousands hosts. For example if one network with 1000 computers connected to internet and entered to one of that network ID, due to the capacity of the network available is only 1000 from the  65.536 host address available, that means there will be more than 64.000 IP address would be wasted (isn’t too dear? ).

Therefore the concept of this IP address classes was made in order to overcome that problem. IP protocol, for example, it could separate 5 different address classes : A, B,C,D and E where each class from the first three class ( A to C ) would have different size to determine the ID network portion and the ID host.

Class D is used for more specific purpose, which called multicast address.

Class E is only the experimental thing and it is hardly used

The first Four bit of these IP addresses are used to determine the IP address classes

1. If the first bit is 0, then the address would be =  A class address.

2. If the first bit is 1 and second bit is  0, then the address would be  = B class address.

3. if the first two bit is 1, and third bit is  0, then the address would be = C class address.

4. If the first three bit is 1 and the fourth bit is 0, then the address would be = D class address.

5. If the first fourth bit is 1, then the address would be = E class address.

C class addresses.
In C class address, first three octet were used for ID network, fourth octet was used for  ID host. With only 8 bit for ID host, each C class network would only be able to cover 254 hosts. However with the remaining bit, which is 24 bit ID network, C class address would be able to cover more than 2 million network.

So, how about the IPV6?
IPv6, also called IP next generation, or IPng, this used to respect the favorite TV program of many internet experts; Star Trek: The Next Generation.
