SIDN’s Whois service enables anyone who is interested to obtain certain information about a registered .nl domain name, such as the name of the registrant. Information about how the Whois works is available here.
With effect from 12 January 2010, SIDN has reduced the amount of information that the public Whois gives about each domain name. The background to the change is explained here. The main difference is that the following contact details are no longer available:
The changes make it difficult for investigative and enforcement authorities to operate in their usual way. Such authorities have the statutory power to require SIDN to provide all the information it has concerning a domain name.
To avoid the need to process information requests individually, SIDN supports automated Whois access for investigative and enforcement authorities. Such authorities have the opportunity to enter into an agreement with SIDN, under which they can obtain both the Whois information that is available to the public and the information referred to above, which the public cannot see. The agreement stipulates that this special access can be used only in cases where the authority has the power to require SIDN to provide the data in question.
A copy of the standard agreement on access for investigative and enforcement authorities is available here.
SIDN currently has access agreements with the following investigative and enforcement authorities:
