query-source and listened interfaces

[Petr Menšík]

Hi Xinyu.

Why would you need client-facing IP address to appear on authoritative
servers? It should be more or less independent.

I think it might be possible to use views and match-destination combined
with query-source for each view. But it seems similar to running
separate bind instances. I think it would have different cache anyway.

Can you share why source addresses are important?

Cheers,

Petr
