What is IP 127.0. 0.1 used for?
It is also known as localhost. When a server is running on your local PC, it will be accessible at 127.0. 0.1. This IP address is reserved for loopback purposes and is not used to communicate with other devices like a real IP address.
Why is 127.0. 0.1 localhost?
The term localhost is usually used to refer to the local computer with the loopback address 127.0. 0.1. As such, typing 'localhost' in the browser's address bar will connect with the device itself. The purpose of localhost is to serve as a domain name for 127.0.
What is the difference between my IP address and localhost?
Localhost is a hostname that refers to the local machine currently making the request. On many computers, localhost is an alias for the IP address 127.0. 0.1. When a computer pings this IP address, it is communicating with itself.
