CENTR

CENTR is an association of European ccTLD registries. CENTR and its members are jointly responsible for 80 per cent of all registered country-code domain names in the world. We are active members, with one member of our team co-chairing the Technical Working Group, while an SIDN Labs team member co-chairs the R&D Working Group.

In 2025, CENTR organised various workshops in Europe, devoted to security, DNS abuse, inter-ccTLD collaboration and the migration to cloud technology. SIDN is actively involved with CENTR and nearly always represented at the workshops.

In 2025, the Chamber of Commerce Enterprise Days took place on 14 and 15 November at Utrecht’s Jaarbeurs exhibition centre. We teamed up with the Benelux Office for Intellectual Property (BOIP) and the Chamber of Commerce to deliver 2 inspiration sessions on the importance of having a recognisable domain name and protecting your brand. We also answered visitors’ questions about domain names, cybersecurity, websites, e-mail and hosting in conjunction with 4 .nl registrars – Compra, Yourhosting, TransIP and Superspace.

European TLD ISAC

We were part of a 12-strong consortium that set up the European Top-Level Domain Information Sharing and Analysis Centre (TLD ISAC). Since its formation in 2023, TLD ISAC's membership has increased to stand at 23 by the end of 2025.

TLD ISAC pools cybercrime-related insights, knowledge and experience. By sharing such information with each other, consortium members can protect their services and the critical infrastructure more effectively and enhance the security of Europe's top-level domains. Read more about TLD ISAC.

Hello Registry

We have joined forces with CIRA, the registry for Canada’s .ca domain, to develop Hello Registry: a unique registry platform that we’ll use for .nl, .ca and numerous other top-level domains. By doing so, we are helping to increase the security, resilience and quality of the internet, while also reducing costs for ourselves and the other registries concerned. Collaboration, knowledge-sharing and impact maximisation are central to those activities. Income from our work as a registry service provider is used to continue developing the platform and investing in our services and in the quality of the internet – yielding benefits for .nl registrars and Dutch internet users.

ICANN

The Internet Corporation for Assigned Names and Numbers (ICANN) performs a number of important internet-related tasks. It distributes IP addresses, for example, and decides the policies governing the issue of gTLDs, such as .com, .net and .shop. One particularly significant function for SIDN is management of the 'root' and the root server system, which is done by ICANN's affiliate IANA. We play an active role in several working groups, particularly the ccNSO (country code Name Support Organization), the body for country-code registries within ICANN.

In 2025, we linked up with the Dutch government's economics ministry to organise a pre-ICANN session for stakeholders in the Netherlands. We also attended the 3 ICANN-meetings: ICANN82 in March in Seattle, USA, ICANN83 in June in Prague, Czechia, and ICANN84 in October in Dublin, Ireland. Like the previous year’s meetings, the 2025 ICANN meetings were dominated by the new gTLD application window that will open in 2026. Efforts to tackle internet abuse also received a lot of attention. At ICANN83, SIDN Labs delivered a session about post-quantum cryptography in the DNS. At ICANN84, we held meetings about Hello Registry and we had a stand promoting the new platform, enabling us to discuss the initiative with registries, registrars and others. Read more about ICANN.

IETF

The Internet Engineering Task Force (IETF) works on evolution of the internet protocols and internet architecture, and on optimising the internet's performance. Various network operators, designers, vendors and researchers participate in this international community, membership of which is open to all.

In 2025, the IETF held 3 meetings. IETF 122 was in March in Bangkok, Thailand, IETF 123 in July in Madrid, Spain, and IETF 124 in November in Montreal, Canada. At the meetings, SIDN Labs made presentations on topics including ForSale, post-quantum cryptography and the RESTful Provisioning Protocol (RPP). We also continued the development of RPP through the IETF working group set up in 2025. Our co-authorships included new internet concepts and an RPP prototype. Read more about the IETF.

Internet Governance Forum

The United Nations' Internet Governance Forum (IGF) brings stakeholder groups from all over the world together to discuss internet governance and digital policy. As a member of the Dutch Internet Governance Forum (NL-IGF), where we collaborate with the Ministry of Economic Affairs and ECP, we attended the twentieth edition of the IGF in 2025, which was held at Lillestrøm, Norway. Its theme was Building Digital Governance Together, and the topics discussed included cybersecurity, digital rights, sustainable and secure innovation, and digital collaboration. In June, the NL-IGF held its annual preparatory meeting.

The IGF also provided important input for the World Summit on the Information Society (WSIS)+20 in December 2025. One of the focuses of the summit was an evaluation of 20 years of international cooperation on digital inclusion, security and internet governance. As a member of the Technical Community Coalition for Multistakeholderism (TCCM), we provided input to the WSIS+20 consultation process. Through the NL-IGF, we liaised with policy development personnel at the relevant ministries of the Dutch government, helping them to formulate Dutch input to the WSIS+20. Read more about the IGF.

Public-private collaboration on online content moderation

Hosting service providers, registrar platform operators, social media platform operators and SIDN hold regular meetings with relevant public bodies to discuss ways to optimise the removal or blocking of illegal content. An initiative by the Dutch government's justice ministry, the meetings are part of the European Digital Service Act regime. A low-threshold reporting system for internet users is also being developed. Read more about collaboration on content moderation

In December, SIDN Labs partnered with RIPE NCC, Young ECP, NL IGF and the University of Twente to host a workshop called How the Internet Really Works. At the workshop, 25 students and young professionals with policy development and technical backgrounds discussed topics such as internet fragmentation and centralisation. One member of our team also sits on RIPE NCC’s DNS Working Group. Read more about RIPE NCC.
