Private IP addresses are :

  • Loopback Addresses: The whole subnet 127.0.0.0 to 127.255.255.255 are reserved for loopback addresses. These addresses are used to test a network card or integrated chip system. In the real world, we only use the 127.0.0.1 address to check the Network Card. But, the whole subnet is reserved as a loopback address.
  • The 0’s Subnet: In IPv4, addresses from 0.0.0.0 to 0.255.255.255 are reserved and can not be used in communication. Actually, we never saw any use of such IP addresses in the real world.
