Loopback is use for testing purpose its a cisco catalyst the loopback address is 127.0.0.0. Its like duplicate address we need to ping particular network. Pathfinder: kingmaker 2 0 3. TCP/IP networks specify a loopback that allows client software to communicate with server software on the same computer. Users can specify an IP address, usually 127.0.0.1, which will point back to the computer's TCP/IP network configuration. The range of addresses for loopback functionality is the range of 127.0.0.0 to 127.255.255.255. 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. An address that sends outgoing signals back to the same computer for testing. In a TCP/IP network, the loopback IP address is 127.0.0.1, and pinging this address will always return a reply unless.
A loopback address is a special IP address, 127.0.0.1,reserved by InterNIC for use in testing network cards. This IPaddress corresponds to the software loopback interface of the networkcard, which does not have hardware associated with it, and does notrequire a physical connection to a network. The loopback addressallows for a reliable method of testing the functionality of anEthernet card and its drivers and software without a physical network.It also allows information technology professionals to test IPsoftware without worrying about broken or corrupted drivers orhardware.

To test a network card using the loopback address, you can use theTCP/IP utility Ping. The best way to do this is with thePing utility that comes with most operating systems. This is a simplecommand-line utility that will try to communicate to an IP address.

Loopback Address Commands
If the command is successful, the Ping utility will return resultssimilar to the following. The exact information returned will varydepending on your operating system:
This indicates that the network card and drivers are functioningproperly. If the Ping utility is not able to get a return on thenetwork card, this may indicate either a driver problem, or a physicalproblem with the card.

Loopback Address 169
The IP address range 127.0.0.0 – 127.255.255.255 is reserved for loopback. Loopback IP address is managed entirely by and within the operating system. These addresses enable the Server and Client processes on a single system to communicate with each other. When a process creates a packet with destination address as loopback address, the operating system loops it back to itself without having any interference of NIC.
Data sent on loopback is forwarded by the operating system to a virtual network interface within operating system. This address is mostly used for testing purposes like client-server architecture on a single machine.
Loopback Address Ip
For example, if a host machine can successfully ping 127.0.0.2 or any IP from loopback range, implies that the TCP/IP software stack on the machine is successfully loaded and working.
