127.0.0.1 is the loopback Internet Protocol (IP), the address is used to establish an IP connection to the same computer being used by the end-user.
The some reason that a person will command a ping 127.0.0.1 in a command prompt is because they will check if the NIC and drivers implementation is functional and it used in testing the TCP/IP.
Answer:
- To check if the NIC functions as expected
- To check if the TCP/IP protocol suite is installed properly
Explanation:
Ping is a command or diagnostic tool that allows you to verify the status of a specific connection or local host. We show their uses.
If you are familiar with the language of networks it is very likely that you have encountered the letters Ping, an acronym for Packet Internet Groper, which literally in Spanish would be "network packet search."
In essence, Ping is a command or diagnostic tool that allows you to verify the status of a particular connection of a local host with at least one remote device contemplated in a TCP / IP type network.
It is used to determine if a specific IP address or host is accessible from the network or not.
The IP address 127.0.0.1 refers to localhost that is nothing other than the local host. But ... What is the local host? As the host is the way to name the team itself, a host is a computer or server ... there is no more mystery.
But let's continue with that of IP 127.0.0.1, this IP address is also known as the loopback IP address that again refers to the local host.
So what is this for? It has several applications but without a doubt the most widespread is to access services from the host itself, for example, you install a WEB service, or an FTP service on your PC and want to access the service, because from your own PC you could do it through the IP address 127.0.0.1 that points to itself, this task is usually carried out just after installing WAMP for example, once installed you open a browser and access the IP 127.0.0.1 , if everything goes well you will access your website or whatever you have installed.
