*Which IPv4 address range is fixed for loopback*
The IPv4 address range that is fixed for loopback is 127.0.0.0 to 127.255.255.255. This range is reserved for the loopback interface, which allows a device to send packets to itself. Any IP address within this range can be used as a loopback address, but the most commonly used loopback address is 127.0.0.1.
When a device sends packets to a loopback address, the packets are looped back to the device’s own network stack rather than being sent out on the network. This is useful for testing network applications and troubleshooting connectivity issues.
