However, you can bypass this wait time by manually updating your <strong>hosts file<\/strong>, forcing your system to resolve the domain to the correct IP instantly.<\/p>\r\n\r\n\r\n<h2>How to Modify the Hosts File<\/h2>\r\n\r\n<h3>Step 1: Locate the Hosts File<\/h3>\r\n<p>The hosts file is a system file that maps domain names to IP addresses locally.
