![]() ![]() Properly put, âthereâs no place like 127.0.0.1â :). I hope this article has helped you learned more about localhost, what its IP address is, and how it works to serve websites for local testing.Īnd yes! Thereâs no place like localhost. If you use with the live server extension of VS Code, it uses a port 5500 attached to 127.0.0.1, followed by the filename: So if you type localhost:4000 in the browser address bar and hit ENTER, the web application youâre currently making will be served to you:Īlso, if you type 127.0.0.1:4000, you will get the same response: That thing is the port number.įor example, in an Express app, that port number is the port variable you set. So, something has to follow localhost: and 127.0.0.1. Remember that the website domain name is what follows the http or https, for example, and. Just like HTTP and HTTPS, the localhost is a protocol. This 127.0.0.1 IP address is reserved for local servers on computers, so you will never find another IP address that starts with 127. ![]() Every device on your network, including the router, will be assigned an internal IP address, but. So, if you type localhost to your browserâs address bar, it transforms to the IP address 127.0.0.1. Open Terminal (Press Command + Space and start to type Terminal) Type in: ipconfig getifaddr en0.

If youâve served a website on your computer so you can test it without connecting to the internet, what youâre dealing with is a localhost. These are what I refer to as âremote hostsâ or virtual servers. If youâve put a website on the internet before, then youâve dealt with hosting companies like Heroku, Hostinger, Netlify, and many others. The IP address for that loopback is 127.0.0.1. Just like you can put a website on the internet by hosting it on a server, you can make your own computer that server. In computer networking, host means a âserverâ. In this article, you will learn what localhost is alongside its corresponding IP address, â127.0.0.1â. You might be using it to test websites and web applications locally without knowing what exactly it is. If you are an experienced web developer, then youâve likely seen the term âlocalhostâ on many occasions.Īnd even if youâre a beginner and just getting started in web development, you might have seen the number â127.0.0.1:â while using a live server plugin. ![]()
