What is localhost?

localhost is a networking term; it’s the hostname for the loopback network interface of whichever server it’s said in reference to (meaning every server has a ‘localhost‘). The loopback interface bypasses any local network interface hardware, and serves as a method to connect back to the server itself. The term localhost is used often in both networking and in server administration.
