NLnet Labs is a not-for-profit foundation with a long heritage in research and development, Internet architecture and governance, as well as stability and security in the area of DNS and inter-domain routing.

We can only do this work with the support of our community. Over the years, we haven't just received donations, but also server and networking hardware, connectivity and of course countless code contributions to our various projects.

We would like to pay special tribute to the these organisations for their long term and significant financial contribution.

SIDN and NLnet Labs have established a long running partnership on technical cooperation. The first five-year agreement was established in 2012 and extended for another five years in 2017. This means NLnet Labs will be focusing more specifically on new technical developments with the potential to support SIDN's services. Building on the close research partnership with SIDN Labs, progress will be sought in fields such as the performance of the DNS and intelligent DNS anycast services.
