But this way is still "global", my need is "per request"

That's my goal :)

Thank you, I'll look to the documentation

I manage a linux device which is the default gateway and DNS server for a
LAN in which there are some device that need to use this service

https://www.unblock-us.com/

which (through a set of DNS server) is used to avoid geo restriction on
some apps (such as netflix)

But for other devices (the ones from http://www.sonos.com/ which have apps
for Spotify and so on) using those DNS instead of normal recursion is not
good

So what I want is using my usual recursor or forwarding all request to a
third party DNS server based on source IP (devices are statically allocated)

Best regards
