How Nginx behaves with "proxy_bind" and DNS resolver with non matching ip versions between bind ip and resolved ip?

I'm working with the proxy module, and with a dns resolver configured. The
traffic i'm using is both ipv4 and ipv6.
I'm trying to understand Nginx behavior when using "proxy_bind" directive
and when the resolver returns both ipv4 and ipv6 addresses.
In particular i'd like to understand what happens when:
1. "proxy_bind" binds to an ipv6 address, and the resolver returns only ipv4
addresses (and the other way around - binding to ipv4, resolving only to
2. "proxy_bind" binds to an ipv6 address, the resolver returns both ipv4 and
ipv6 addresses, but the first attempted ip address is an ipv4 address (and
the other way around - binding to ipv4, first attempted is ipv6).
Can you please shed some light on this?
