With so much at stake, making changes to your DNS records can be a nerve-wracking experience. Fortunately, there is a way to test DNS-related changes without editing your live records. By modifying your local hosts file, you can preview how your domains will function on a new server without putting your live site at risk.

A hosts file is a local plain text file that maps your server or hostnames to Internet Protocol IP addresses. This is the process used to obtain the server IP address behind a domain name.

Each hosts file entry has its own line, with the numerical IP address, a space or a tab character, and finally the hostname or domain. In the above example, the first section denotes the IP address where this request will be redirected to The second section designates the location that we want to redirect a request from example. The final section specifies a comment for this entry. After adding the domain information, your system will resolve to the IP address you specified.

DNS is the key to locating a website. When you modify your hosts file, it causes your local machine to look directly at the IP address specified by you. For example, if you wanted to point mywebsite. Now, every time you try to visit mywebsite. By editing your hosts file, you can override the DNS for a domain on your specific machine only. However, it is also possible to replace this file entirely.

You might take this a step further and block all websites that serve up advertisements. If you map the addresses of all the major ad providers to an unused internal IP address, then Windows 10 will be unable to resolve these addresses.
