Windows includes a local ‘Hosts’ file that contains domain names and matching IP addresses, acting as a map to identify and locate hosts on IP networks. Every time you visit a website, your computer will check the host’s file first to see which IP address it connects to. If the information is not there, your internet service provider will look into the DNS for the resources to load the site. Hosts files have existed since ARPANET time and were used to resolve hostnames before DNS was introduced. These files aid in network name resolution. The syntax is consistent across all platforms. it is worth noting that, most host files will have several entries for loopback. In this guide, you will learn to locate and edit the host file on Windows.

C:\windows\system32\drivers\etc\hosts

Select a Text Editor to have the host file opened. I have also created a record for test.techdirect.local. When you are done, click on save and close the text editor.
