Support,

Not sure what I am doing wrong. But I cannot figure out how to map IP address on my client with a host name on my Dynu account.

Client Image attached.

You can assign different group names to the hostnames in the control panel. Then you can use the group name in the IP update client login page to update one particular host which belongs to that group.
