Struct SystemResolver 

pub struct SystemResolver;

The system resolver: an IP literal in place, everything else through getaddrinfo.

What it answers is A and AAAA records, so the whole set shares one port — the one the URL wrote, or DEFAULT_PORT when it wrote none. That covers a literal, a plain name and a Kubernetes headless Service, whose A/AAAA answer is the set of Pod addresses. It cannot express a port-forwarding load balancer; Resolver is how that deployment brings its own answer.
