What is Localhost or 127.0.0.1 and why it is said that there is no place like 127.0.0.1

Today in this article we will discuss about what localhost or 127.0.0.1 is. Though it is a very easy topic, many computer users still have the confusion on what this localhost really is. And we will also discuss why it is said that there is no place like 127.0.0.1.  

Actually the computer we use is a localhost. It may sound strange to some people those who are seeking for a right answer on internet but it is true that this ip 127.0.0.1 is local host of whatever computer you are in front of. It is actually the local ip address of your computer or loopback address that can be used as practical on networking. Many pentester or Ethical hackers use this local network to do their practical studies. As you all know that if you try any hack attack on any network or web server without a proper permission it is totally illegal and such hack attacks called black hat hacking. So ethical hackers or pentesters often try different hack techniques on this local host or local server which is totally legal and needs no permission from anyone. It is something like you are performing a hack attack on your own network or server. But before using it you have to set up your localhost if you want to try something on it.  

The word Localhost carries a special meaning in computer networking field. The localhost or loopback address is only used by the computer you are on, and only for special circumstances. Actually the localhost or 127.0.0.1 is not like the regular ip address we use to transfer files from one networked device to another networked device.  





Any web server running on a computer can also be run on 127.0.0.1 so that the pages can be run locally. In this way anything you want to test on a web server can also be tested locally. Computer network security analyzers also use this localhost to improve network security.  


Hope you have cleared all your confusion from this article. Now we will discuss why it is said that there is no place like 127.0.0.1. Well it is just like we say that there is no place like home. Because home is like a safest place in the world. When we are at our place we feel safe and comfortable, just like that there are no risks when you are testing something on your localhost. It is probably the safest place where you can perform everything very comfortably without any risks because it is your local server from where nothing goes out. So hackers often say that there is no place like 127.0.0.1
