balancing tool that is not PowerDNS specific.  The project is very fresh,
which is why we'd appreciate any input on useful features within our chosen

It has lots of Lua hooks to implement just about anything dynamic, and at
pretty good speeds too (but see the post for full details).

Introducing dnsdist: DNS, abuse- and DoS-aware query distribution for
optimal performance

life is to route traffic to the best server, delivering top performance to
legitimate users while shunting or blocking abusive traffic.”
