Wildcard DNS

Wildcard DNS is a non-caching, non-recursing DNS server that serves authoritative answers for A, AAAA, NS, PTR, CNAME, SOA and MX resource records. It is designed to answer with the same resource records for a variety of domain names (wildcarding). It is not limited to wildcarding, DNS zones can be configured individually. It serves both IPv4 and IPv6.

Originally wildcarddns was meant to sit on firewalls with authpf but caching dns resolvers on client boxes didn't work very well with it. So now I'm trying to figure out what purpose wildcarddnsd should have. Most functionality is finished on what it should have become and it's unlikely that there will be much more.
