DNS server for blacklisting tons of domains and also some TLDs

I'm trying to setup a basic DNS server for my lan that is able to put in a nullroute or 127.0.0.1 lots of domains. The domains I want to block come from a list but I also want to block some domains using regular expressions (this is a must for my setup). My candidate software for doing this business seemed to be Unbound, a recursive caching secure DNS server with various useful functions. **However Unbound doesn't seem to support any regular expression!** Also, Unbound is very picky when it comes for zones repetitions. My domain list is builded from many mixed sources so I can have many repetitions that I filter out with some scripts but also domains in list like: **aaah.very.this.com** but also **very.this.com** This lead Unbound scream for errors because there is a zone repetition. While this is a minor issue, that I can remove by cleaning even better the domain list, my main issue is the lack of regexp for handling the domain requests. Can i somehow block all *.com or *.biz or stuff like that? [\w\.\-]+.com A 127.0.0.1 [\w\.\-]+.com AAAA ::1 My regex is an example, i could go with more complex ones... BONUS ----- Can I instead do something even more nasty? Have everything pointing to nullroute or 127.0.0.1 and ONLY a whitelist of domains get resolved by being forwarded to an external DNS ? If replying please do not forget this extra question as I am very interesting in knowing the answer. **What i can go for? Bind9, dnsmasq, unbound, pdns-recursor...**
