A new version of dnscheck.norid.no will be launched shortly. Norid now uses the test tool Zonemaster, which has been developed in a collaboration between the registry IIS (.se and .nu) and AFNIC (.fr).
In the meantime, you can test the service here: https://zonemaster.norid.no/.
When the new service, based on Zonemaster, is launched, it will be moved to dnscheck.norid.no.
