Having it in the system will help other applications to do DNS queries faster (e.g., asterisk, mail servers ...). It looks to be really powerful being able to cache many services, not only DNS. It comes packaged with most of common distributions.

It was dnsmasq (also found almost in every distribution) if you don't
want to use bind in cache only mode. If you use dnsmasq put your

won't be forwarded, only locally configured SRV request will be
answered.
