Wildcarddnsd
From Hackepedia
Wildcarddnsd 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 with minor patchwork on Mac OS X. NetBSD may also work.
The Wildcarddnsd homepage is found at centroid.eu.
Development
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.
