NO-IP is a dynamic dns service that allows you to redirect a domain to a dynamic (usually ISP-assigned) IP public address. You can't use it for private LAN addresses as you are attempting to do. The 172.16.0.0 range is a private range which isn't routable over the internet.
The administrator has disabled public write access.
