Open source software

We develop and contribute to a number of free/libre and open source software packages as part of providing these services. Much of our software is also used by other organizations around the world.

  • We are frequent contributors to the DNS server software ISC BIND

  • We wrote nsdiff which is a key part of our DNS update mechanism.

  • The nsnotifyd program can run a script when a DNS zone changes.

  • Our DNS-over-TLS and DNS-over-HTTPS service uses doh101

  • Secret keys and passwords in our configuration management system are encrypted using regpg
