How can I resolve the "Your IP is not allowed" error when I try to login to Cin7?

When I try to login to Cin7 I receive the following error:

"Your IP is not allowed"

How can I resolve this error? 


Please contact an admin user for your Cin7 account if you see this error.

Please note that you can only add Public IP addresses for your domain in the Allowed IP Address field under user Access Settings. You can get public IP addresses from the domain administrator.
