The Norid EPP service is protected by an IP filter which restricts access to the service to the address blocks which are registered in the registrar web (https://registrar.norid.no).
On Tuesday March 10. we will narrow this filter so that each registrar can only access the service from the address block that they have registered for their own use. From what we can see in our system logs we do not think this change will cause any problems to the clients which are currently being used. Nevertheless, we ask you to ensure that the address blocks that you have registered in the registrar web is correct and includes all your client machines being used to access the services epp.norid.no, eppclient.norid.no and registrar.norid.no.
