Example of internet address

IPV4 address

In IPV4 addressing system 32 bits is used for representing each addresses. These 32 bits are parted into 4 octets. By ' • ' sign each of the octets are divided. 

From the I address first two octets (first 16 bits) is the network ID of the address and next two octets (last 16 bits ) is called host ID.
