the function of loopback to connect to tcp/ip in networking
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.
The problem with your IP address lies in the first octet. 127.0.0.1 addresses are reserved for loopback addresses.
ping 127.0.0.1 CompTIA A+ page 972
The loopback address for each machine is 127.0.0.1, regardless of how many machines are on the network.
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"
There are several IP addresses that are special in one way or another. These addresses are for special purposes or are to be put to special use.Addresses significant to every IP subnet Network AddressBroadcast AddressAddresses significant to individual hosts Loopback AddressSpecial Addresses of Global Significance Private AddressesReserved AddressesLOOPBACK ADDRESS (127.0.0.1)The 127.0.0.0 class 'A' subnet is used for only a single address: the loopback address 127.0.0.1. This address is used to test the local network interface device's functionality. All network interface devices should respond to this address. If you ping 127.0.0.1, you can be assured that the network hardware is functioning and that the network software is also functioning.

Addresses are not important for societies to function, but they do serve very important purposes. Addresses help cities and counties know who should pay city or county tax.
How many possible host addresses are there in a Class A range?Class A range is 0 - 1270.0.0.0 and 127.0.0.0 are not "routable" IP addresses. One defines all networks and the other is the loopback. We have a total of 126 usable networks and 16,777,214 usable hostaddresses per network.
The only difference is the relative location of the device that is in loopback mode. Local loopback testing is when your device is set to send back everything it receives to the sender, aka loopback mode. Remote loopback testing is when your device orders a foreign device to enter loopback mode.
This IP address is usually called the localhost address.
Rollback is a feature in database management that allows reverting changes back to a previous state if needed, while loopback is a type of network configuration where data sent out to a network is looped back to the sender without leaving the local system. These terms are used in different contexts and serve different purposes in computer science and networking.
