I have two domains,
One in a group called 7401 running the client logged in as user/pass/7401.

The other domain is at another location setup in an Arris router. This domain is not in a group but curious if this is the best setup. Is there a way to join the second domain in a group and point the router to that group. I'm currently using the below in the Arris for the non-grouped domain.

Server: api.dynu.com
Hostname: yourhostname
Username: your Dynu username
Password: your Dynu password

The current setup in the Arris router does not require a group to be set up but it is best that you do assign the hostname used in the Arris router to a separate group called Arris. This way the Arris hostname's update does not get affected by others.

Thank you! I assume that if I had more than two hostnames assigning that group "arris" would matter more. Thanks again for the help.
