Delphinusdnsd is a DNS Server. It was previously named wildcarddnsd, but renamed to avoid confusion. The first release was made on January 1st, 2016.
Delphinusdnsd's codebase was 10 years old in late 2015. It was written under the wildcarddnsd name in November 2005. Development has been ongoing since then and many features and protocols were added (and some removed).
