24hrs for dns to update? No, only the first time can takes up to 72hrs, after that only seconds.
If you set up your dns and vh correctly, you will see your pages running on your computer shows up when type in the browser your domain name.
For example, you can only see this page below only when I turn on my computer

To set up dns or vh, search this forum for DNS or VH, you might run into some of my old post or better from CyberSpatium.
Hope this help.
