Access to Tamago-DB can be limited by public IP address on an agency-wide or per-user basis.  Only Admins and Super Admin can restrict IP addresses. 

To determine your public IP address is, see  Google will display your public IP address as the first result.

Note that your private IP address and public IP address will likely differ.  Your private IP address is internal to your local network. Your public IP address is the address that is broadcast when you are connecting to services like Tamago-DB.  (Private IP addresses often begin with 192.###.###.###)

To set an IP address restriction, edit the "Allowed IP addresses" field for either the agency or an individual user.  Separate multiple IP addresses with commas.  Changes made under Administration setting will affect all users.  Changes made for an individual user profile will only affect that user.
