FAQ

What is the Host File Used For?

The host file is used to map hostnames to IP addresses. When you type a hostname into your web browser’s address bar, your computer looks up the corresponding IP address in the host file. If the hostname is not listed in the host file, your computer will query a DNS server to resolve the hostname to an IP address.

Can I Delete the Host File?

No, you should not delete the host file. It is an important system file and deleting it can cause network connectivity issues.

Can I Rename the Host File?

Yes, you can rename the host file if you wish. However, if you do so, your computer will not be able to locate the file when it needs to resolve hostnames to IP addresses. If you do rename the host file, be sure to update any applications or scripts that rely on it.

How Do I Reset the Host File to its Defaults?

To reset the host file to its defaults, you can delete the existing file and replace it with a fresh copy. Alternatively, you can open the host file in a text editor and remove any entries that you have added manually.

What Happens If There is a Conflict Between the Host File and DNS?

If there is a conflict between the host file and DNS, the host file takes precedence. This means that if there is an entry for a hostname in the host file, your computer will use the IP address listed in the host file instead of querying the DNS server for the IP address.
