So, we have subtracted two from the actual number. These special IP addresses are not assigned to any host in the network. The IP address with all host bits as zeros and all host bits as ones are special IP addresses.2^h is the number of unique IP addresses that can be formed by h number of bits.It is the number of hosts (connected devices) present in the network or subnet. Remaining bits (h = 32-n) are used to identify the host in the network. The number of these bits is called as netmask (says n). Some of the starting bits in the 32 bits IP address are used to identify the network. There are multiple benefits of subnetting. Subnettingįor the sake of simplicity, there is a provision to divide the network into multiple subnets. Read detail about different IP address class types and their uses. This classification is based on the starting bits of the first octave IP Class TypeĪll the IP addresses are classified into five types called class A, class B, class C, class D, and class E. You can read the difference between IPv4 and IPv6 addressing. Where x is in the range of 0 (00000000) to 255 (11111111).īy default, IP address is considered as IPv4 IP address. It is 32 bits address and split into four-octave. This IP address is a part of the network layer (3rd layer in the OSI layer model architecture). The IP (Internet Protocol) address is the address assigned to the device (computer) by which other devices identify it.
