SIDN’s main role is acting as the ‘registry’ for .nl – the Netherlands’ country-code top-level domain (ccTLD). The .nl domain is widely recognised as one of the world’s best ccTLDs. Using the knowledge and experience gained in our main role, SIDN also provides ‘registry services’ for other top-level domains, such as Aruba’s country-code domain .aw. We provide management solutions for trust frameworks as well. We are also active in the development of products and services that contribute to internet security.
