When setting up a network that will consist of many host computers, one of the first things that an administrator must do is to determine what class of networks that they must administer to a given business. This is the point where every administrator must know how to implement classful and classless IP addressing. A classful network is a network addressing architecture used in the internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Classful IP addressing divides the addtess space on the internet into five address classes. Each class is coded in the first four bits of the address. Today

If we take the 172.16.0.0 range, that is /12. So that means that the network mask is 255.240.0.0. If we take 256-240 = 16 we get the block size which is 16. So that means that the range is from 172.16.0.0 to 172.31.255.255 because 172.32.0.0 is the next block and would be a public IP.

It is expressed as a dotted decimal number format to make it easier for human beings and the computer to remember.

In CIDR notation, the IP address and subnet mask 191.9.205.22 255.255.192.0 are written as. B

If you used the number of bytes instead you would get a whole different amount of possible networks which isn’t right.

(11111111.11111111.11111111.00000000). Everything to the right stays a 0 indicating the number of host in each subnet. Everything to the left becomes a 1. The new subnet mask is 255.255.255.0. You get this number by adding the 1’s together in each octet (128+64+32+16+8+4+2+1=255).

Seven bytes are allocated in a DATE column to store the century, year, month, day, hour, minute, and second of a date. _________________________

As the population is going on increasing day by day the usage of the internet using people also had been increased drastically, which in return resulted in the shortage of ipv4 IP addresses, so in order to overcome this scenario the Internet Engineering Task Force which works for the development of internet technologies has developed IPV6 for usage of internet for more number of users and devices.

Ipv4 remains for Internet Protocol form 4. It is the underlying engineering that makes it workable for us to interface our gadgets to the web. Ipv4 utilizes a 32-bit location space, in which can suit around 4 billion remarkable locations. While that sounds generous, the functional number of usable locations is really much lower. The current Internet has become much bigger than was anticipated. There are a few issues, for example, approaching depletion of the Ipv4 location space, arrangement and complexities and poor security at the IP level. (PARR, 2011)

Class A addresses are assigned to networks with a very large number of hosts. The high-order bit in a class A address is always set to zero. The next seven bits (completing the first octet) complete the network ID. The remaining 24 bits (the last three octets) represent the host ID. This allows for 126 networks and 16,777,214 hosts per network. Figure 7.1 illustrates the structure of class A addresses. The range of IP addresses is 0 to 127.
