Why the .dev top level domain? Can’t I use a .com tld?

You can specify any top level domain you want (.com, .net, .org, .info, etc.) when exporting to a live server using DesktopServer Premium edition. We enforce the fake .dev domain for development to insure security, avoid confusion, and prevent conflicts with real servers. Network and system administrators frown upon overriding real DNS servers because of the security implications with DNS spoofing, not to mention support attempts determining which content is the real top level domain makes the .dev pseudo domain the best solution. DesktopServer Premium manages the replacement of .dev when importing and exporting sites.
