I have 2 separate host setup that I need to update from different locations (ip addresses). Your IP update utility updates both host with the same IP address. Is there a way for me to specify what host gets updated?

Setup a 'Location' for each host and specify that 'Location' in the IP update utility. The IP update utility will only update the IP address hosts whose 'Location' is specified in the utility.

You can assign each host to a 'Location' at https://www.dynu.com/en-US/ControlPanel/DDNSLocation

Worked great, Thank you!!!
