What is a Localhost and LoopBack IP: Everything You Need to Know
Learn what is a localhost and Loopback IP and how we can use it! Discover all important information here!
Localhost refers to a standard host name that describes the local computer address which is also known as Loopback IP.
In order to understand what a localhost is exactly, you need to learn what is IP address and LoopBack IP address.
What is IP Address?
The IP address is the address of the computer device registered in the internet world or the local computer network. When the computer device is connected to the local network, there must be an address assigned in order to data send by other devices on the network to be delivered successfully.
The IP address is 32 bytes long and it is read in a decimal format, for example, 192. 168. 1. 1. Each portion of the IP address ranges from 0 to 255 which means that the IP can be from 0 to 255.0 to 255.0 to 255.0 to 255.
In practice, the use of 0 and 255 are reserved for subnetting and broadcast purpose, since the actual IP address ranges from 1 to 254.
What is LoopBack IP Address and How LoopBack IP Address Works?
Your local host IP is 127. 0. 0. 1 which is also known as LoopBack IP address. The LoopBack IP address range is suitable for testing and damage control determination at local host level.
This IP is ideal to use if you want to check the stability or health of the network adaptor while connection the computer device to the network. If you can ping the LoopBack IP address successfully, you can rest assured knowing that the network adaptor is stable and it works without a problem.
You can check this by typing ping 127. 0. 0. 1 and you will receive the results. If you want, you can also use the local IP address assigned to your computer device once it is attached to the network.
Another vital use of the IP 127. 0. 0. 1 is that it allows you to access the network services on your own computer device. For example, if you have installed a web server on your computer devices such as IIS or Apache and you want to access a site on your local computer device, all you need to do is to visit localhost or 127. 0. 0. 1 in the search online browser.
A Final Word
We hope that by explaining what an IP address, 127. 0. 0. 1, and LoopBack IP address are, you will be able to understand what localhost is.
Localhost represents a unique meaning in the computer network and it is a term used in combination with 127. 0. 0. 1.
The computer operating systems provide an entry into the hosts file that is associated with the name and the LoopBack IP address. This allows applications to create loopback messages via texts (name) rather than a decimal format.
