the function of loopback to connect to tcp/ip in networking
127.0.0.1

Something you plug into a port/ slot on a computer that tells it there is a network/connection active on the port but, it is just a facade created by the loopback adapter, you see them a lot in IT technicians tool bags
resever ip of loop back is 127.0.0.1
ping 127.0.0.1
The loopback address for each machine is 127.0.0.1, regardless of how many machines are on the network.
The only thing that pinging the local loopback adapter on a host will prove is that the TCP/IP stack is installed and operating correctly. It will not diagnose a faulty NIC.
The problem with your IP address lies in the first octet. 127.0.0.1 addresses are reserved for loopback addresses.
127.0.0.1 is the loopback address in IP.... or in the (slightly modified) words of Dorthy Gale when she returned from Oz "There's no place like 127.0.0.1"
LOOPBACK ADDRESS - 127.0.0.0\8 IP Network range is reserved for Internal Testing.
It looks like you have a network with static ip addresses. You have set up manually an ip address for your network adapter. Just go in the properties of the adapter and put an ip address from the same subnet as other users are using in the network.
