What is the Host File?
The host file is a text file located at C:WindowsSystem32driversetchosts on Windows. It is a file that contains a list of IP addresses and their corresponding domain names. The file is used to map IP addresses to domain names, allowing users to access websites and other online resources using their domain names instead of their IP addresses.
