Wildcarddnsd/Delphinusdnsd is an authoritative turn-key DNS server. It differs from a general-purpose DNS server such as BIND in reduced functionality. However Wildcarddnsd is only 7 year old with only 7.1 human work-years behind it. Compare this with many human resources of BIND development.

Wildcarddnsd runs on OpenBSD, FreeBSD, Linux, and NetBSD, a port for Windows is in future plans.

The old commit sources can be found at gotweb.delphinusdns.org.


The wildcarddnsd daemon is written in the C language. It was developed on OpenBSD and tries very hard to not have an overflow by useing strlcpy/strlcat when possible. Later pledge and unveil were added as well as other goodies found in OpenBSD

Name change

As of Friday November 14th, 2014, the wildcarddnsd project has been renamed delphinusdnsd. The new project is found here:


10 Year Anniversary

In November 2015 delphinusdnsd is 10 years old. In November 2025 (2.5 years at time of this writing) delphinusdnsd will be 20 years old.


The next release of delphinusdnsd will have DNSSEC support. And maybe even TLSA support. Both of these were implemented at the time of this writing (June 5th, 2023)
