Conversely, the protocol does not accept external requests addressed to Packets reportedly appearing on the internet from reserved IP addresses like A loopback device is created so that the back link to your own computer works.

This is a virtual interface that is created through the operating system. With Unix systems, the interface is called lo or lo0 and can also be displayed using the ifconfig command. A similar command for Windows is ipconfig. If you consider the technology independently of the local host, a loopback can be created in an analog way: circuits in communication technology can then be used to determine whether the paths taken by the signal and the reception are correct.

Developers use the local host to test programs and web applications. Network administrators can also use the loopback to test network connections. Another practical use for the localhost is the hosts file, where you can use the loopback to block malicious websites. During development, it is important to find out whether the application actually works as hoped once it has internet access. They can stimulate a connection while also avoiding the network detour: the connection instead just stays completely inside their own system.

Another advantage of using localhost for testing purposes is its speed. When you send a request over the internet, it takes more than milliseconds.

If you send a ping to localhost, the maximum transmission time is just one millisecond. With this technology, you can also find out whether or not the Internet Protocol is correctly implemented.

You can either send it to the domain localhost or directly to the IP address. If you want to set up your own test server on your PC to address it through the localhost, you first need to install the right software. It is generally possible to run any standard web server on your own computer, but there is also special software specifically designed for use as a localhost — XAMPP for example. We provide a step by step guide for how to install and configure the test system in our Digital Guide.

Localhost also plays a role in the hosts file. If you enter a website address in the browser, the domain name needs to be translated into an IP address. It used to be the host file, but today you would usually use the global DNS. However, the host file is still present in most operating systems. This ensures that name resolution for the localhost does not have to be done over the internet.

You can also use the file to block certain websites. To do this, enter the website to be blocked into the list and assign the domain the IP address If you — or perhaps a malicious script — try to call up the locked domain, the browser will check the hosts file first, and find your entry there. Another option is to use the domain name 0. The browser will then try to access the corresponding website on the server with However, it is unlikely that the browser will be able to locate it, because the requested file will not be there.

However, if you have set up your own test server, then the browser may find home. In the control panel, click on the start action for the Apache module.

Is there something to install locally so that I can create my test databases in localhost? You could download a free specialized edition of SQL Server from the link below, then install it on your laptop.

This can be beneficial to other community members reading this thread. You can install developer edition as local instance. Its free for development activities and includes all features as Enterprise Edition.

Only restriction is that it is now allowed for production use. But from development perspective it will provide you with full functionality of SQLServer components. The content you requested has been removed.
