First of all, thanks for your response Bert.

As making it correctly and stable, not just destination ip address also
source ip address should be changed.

Maybe, this can't be done via Lua, but is it possible to do via breaking
the dns packets in PowerDNS source code?

Just wonder if something possible before an Anycast DNS solution.
