How can I access a site in ISPConfig that doesnt have DNS set up at the registrar yet? For instance, lets say www.domain.com is setup and hosted elsewhere, but I want to develop and change www.domain.com on my ISPconfig box before I switch over the DNS and move the hosting. On my H-SPHERE control panel, I have a temp URL that can preview the site without active DNS. How can I do this with ISPConfig?
