![]() ![]() The conversion of localhost into IP address requires a look up table. ![]() The following table highlights all the important differences between localhost and 127.0.0.1 − Localhost Differences between Localhost and 127.0.0.1 In addition, one can use 127.0.0.1 to access the network services running on the local machine. You will be using this IP address frequently while developing web applications because when you type "127.0.0.1" in the address bar of your browser, it will load the local web server's page. 127.0.0.1 is a private IP address that is used to connect with the same device on which the address was entered. 127.0.0.1 is a part of a reserved block of more than sixteen million IP addresses. 127.0.0.1 is used specifically for loopback functionality. The IP address 127.0.0.1 is one of the most commonly used loopback IP addresses. It may redirect to another IP address within the loopback block of addresses. Note that "localhost" needn't always resolve to "127.0.0.1". When you type "localhost" in your browser's address bar, the browser looks up for its associated IP address. We tend to use localhost as the synonym for "127.0.0.1", however, in actual practice, they are not exactly the same. It helps us in spoofing the network connections when such a network does not exist. It is a communication port that is connected to the local server. The localhost allows a network connection to loop back on itself. You can think of it as the domain name for "127.0.0.1". "localhost" is the machine name or IP address of the host server. This article is meant for explain the important differences between localhost and 127.0.01. On almost every machine, the localhost and 127.0.0.1 are functionally the same. ![]()
