To change your domain name’s IPS tag, you will need to do the following:
In the Domain names section, select the relevant domain name in the drop-down list and click on the Manage button.
Click on the Change IPS Tag option.
Enter the new TAG in the space provided.
Click on the Change IPS TAG Now button.
Please note: It normally takes approximately 12/24 hours for this to update. However some providers have a handshake system where they will need to approve the transfer in and therefore the IPS tag may not update automatically. Please check with your new provider if they have this process in place so that they can approve the transfer once you have changed the TAG.
