NLNet Labs develops DNS-related software, such as NSD, Unbound, OpenDNSSEC and getDNS.
NLnet's core business is to support independent organisations and people that contribute to an open information society.
In 2001 the RIPE NCC asked NLnet Labs to write a DNS implementation geared especially to rootservers, but not containing any code of existing software.
[1] On 19 April 2023, NLnet Labs and the Internet Systems Consortium (ISC) sent a joint letter to the European Parliament committee working on the EU Cyber Resilience Act.
The letter is a plea for fairness for non-profit developers of open-source software, because the Act mostly focuses on those who supply products in a business related context, while according to the two organisations the non-profit distribution of open source internet infrastructure software should not be regarded as a "commercial activity".
