Network 127.0. 0.0 is reserved for IP traffic local to your host. Usually, address 127.0. 0.1 will be assigned to a special interface on your host, the loopback interface, which acts like a closed circuit.
What is a 127.0 0.0 address used for?
IPv4 network standards reserve the entire address block 127.0.0.0/8 (more than 16 million addresses) for loopback purposes. That means any packet sent to any of those addresses is looped back. The address 127.0.0.1 is the standard address for IPv4 loopback traffic; the rest are not supported by all operating systems.
