Understanding Host File Location on Windows Server 2019

Hello Dev, welcome to this comprehensive journal article that seeks to enlighten you on the host file location on Windows Server 2019. In this article, we will take a look at the importance of host file location, where it is exactly located on Windows Server 2019, how to access it, and much more. So, let us dive into it.

What is a Host File?

A host file is a plain text file on your computer or server that translates hostnames (such as www.example.com) into IP addresses (such as 192.0.2.10). It is used by the operating system to map human-friendly hostnames to IP addresses that networking equipment requires to communicate with other devices on the network.

While most network communication relies on DNS servers to perform hostname resolution, sometimes the host file is necessary. A host file can be useful if you want to test your website on a new server before pointing your domain name to it, or if you need to access a server that doesn’t have its DNS records set up properly.

Where is the Host File Located on Windows Server 2019?

The host file on Windows Server 2019 is located in the same place as on any other Windows system. By default, the location of the host file is C:\Windows\System32\drivers\etc\hosts.

How to Access the Host File on Windows Server 2019

Now that you know where the host file is located on Windows Server 2019, you may want to access it for various reasons. Here is how to access the host file:

1. Open File Explorer and navigate to the following directory C:\Windows\System32\drivers\etc.
2. Right-click on the host file and select “Open with” from the context menu.
3. Choose Notepad to open the host file.

Understanding the Structure of the Host File

The host file is a plain text file that is divided into two columns separated by a space or a tab. The first column contains the IP address, while the second column contains the hostname. Each entry in the host file must be on a new line, and each line beginning with the “#” character is considered a comment and is ignored by the system.

Here is an example of a host file entry:

IP Address	Hostname
192.168.0.1	dev.example.com

In the example above, the IP address of 192.168.0.1 is associated with the hostname dev.example.com. Whenever your computer or server needs to communicate with dev.example.com, it will use the IP address specified in the host file.

Frequently Asked Questions (FAQs)

What is the Purpose of the Host File?

The purpose of the host file is to translate hostnames into IP addresses that networking equipment requires to communicate with other devices on the network. It is used by the operating system to map human-friendly hostnames to IP addresses.

Why Would I Need to Edit the Host File?

You may need to edit the host file if you want to test your website on a new server before pointing your domain name to it, or if you need to access a server that doesn’t have its DNS records set up properly.

What Should I Do if I Mess Up My Host File?

If you mess up your host file, you may not be able to access the internet or other devices on your network. To fix this, you can restore your host file to its default state by deleting it and replacing it with a default host file. To do this, simply copy the default host file from another Windows Server 2019 machine or create a new one using a text editor and save it in the location C:\Windows\System32\drivers\etc\hosts.

Can I Create Multiple Entries in the Host File?

Yes, you can create multiple entries in the host file. Each entry must be on a new line and follow the same structure as described earlier in this article. To add a new entry, simply create a new line and add the IP address and hostname separated by a space or tab.

Is it Possible to Block Websites Using the Host File?

Yes, it is possible to block websites using the host file. To do this, simply add an entry in the host file with the IP address of 127.0.0.1 and the hostname of the website you want to block. This will redirect the website to your own computer and prevent it from loading.

Conclusion

We hope that this article has given you a clear understanding of the host file location on Windows Server 2019.
