Can't add URL for Support videos API for dev server using IP address?

Is it possible to add Integrated Video Tutorials for use on a dev server that users an IP address instead of a typical top-level domain name?

I'm trying to add it here: http://173.254.79.155/~seattmf6

I need my client to be able to practice and learn without them being in the live environment yet. Help?

Thanks,
Kenny
