Local Host

In the field of computer networks, the local host is a virtual server used on the user’s local computer. The local host is used by developers to test programs and web applications without being on the Internet
Calling the local host is like a computer talking to itself. A local host has the IP address, which refers to the user’s own computer server. In other words, when the user tries to access this domain, a loopback is triggered and the request will not be transmitted to the Internet via the router but will remain in the user’s own system.
