If your system is connected to the Internet by a dynamic Internet Protocol (IP) address, but you need to be able to reach the system with a fixed name, you can use a dynamic Domain Name System (DNS) service, such as the one provided by No-Ip.com. You can install their dynamic update client on the system and it will report its IP address to No-Ip's DNS servers.
If the No-IP Dynamic Update Client (DUC) software on a system is not updating the IP address for the system with
No-IP's servers, you can start and stop the service from the command line (you may need to be logged into an account in the administrator group) by using the following commands:
net stop noipducservice
net start noipducservice
You can determine when a system last updated its address with No-Ip's servers by logging into your No-Ip account and under "Hosts/Redirects", click on "Manage". Locate the name of the system in question and click on "Modify" for it. You will see a "Last Update" for it.
