We have added an extension to the RDAP-service which makes it possible to look up the number of domain names registered on a subscriber.
The query returns the number of domain names registered on a subscriber, given by identity. The query can be used with organization number and person-id as key. The URL for the lookup is:
https://rdap.norid.no/norid_domain_count/987654321
The query returns the number of domain names registered directly under .no as well as the number of domains registered under any sublevel domains.
The function is currently only available in the test version of RDAP, but will be added to the production system on 30 September, when the announced changes in access to customer data are implemented.
Please note that this function is available for authorised users only.
