Each tool that connects to other gadgets to the net is assigned a unique IP cope with. For systems to find each other on distributed networks, like the net, each node at the community is assigned a unique deal with.
This cope with is generally called ‘IP address’ or ‘IP.' The IP deal with is a 32-bit binary address which consists of two sub-addresses that pick out the network and the host of the network. The IP deal withconsists of 4 units of numbers ranging from zero to 255 separated via a (.) in decimal shape. as an example, 192.68.a hundred.4 is a valid IP address.
There are five classes of IP addresses which are:
The first bit of a class An address is always set to 0. It only leaves seven bits for the network portion of the address. Class A addresses range from 0.0.0.0 – 127.0.0.0. It means there can only be 128 network numbers.
The first bit of a class B address is always set to 1 and the second bit is set to 0. It means 16,384 networks can be assigned class B addresses. The numbers range from 220.127.116.11 – 18.104.22.168.
Class C addresses have their first two bits set to 1, and the third bit is set to 0. It means 2,097,152 networks can be assigned this class of address. The numbers range from 192.0.0.0 – 22.214.171.124.
Class D addresses have their first three bits set to 1, and the fourth bit is set to 0. Class D addresses are used for multicasting applications. The numbers range from 126.96.36.199 – 188.8.131.52 and are reserved for multicast groups.
Class E addresses are reserved for experimentation and testing and have never been utilized in any standard form.
