I'm currently developing a security solution that should work across domains and as such I need a small private dns server to add various entries to. I could alter the hosts file to achieve the same result but since the hosts file doesn't support wildcard chars I will have a whole lot of entries, so a DNS server that supports wildcards would be a little bit easier. Any suggestions?
As a reference: http://sourceforge.net/projects/acrylic/
Acrylic is a local DNS proxy which improves the performance of your computer by caching the responses coming from your DNS servers.
I found it to work flawless on every Windows system from XP up to Win8, and it's open source.
And yes, it supports wildcards... it even supports regex for domain names.
