Enum Scope 

pub enum Scope {
    NeverDialable,
    PrivateScope,
    GlobalUnicast,
}

How dialable an address is, as three tiers (SPEC.md §5.2). Exhaustive: adding a variant is a breaking change, since is_usable_reflexive_addr and is_globally_routable are both defined in terms of an exhaustive match over this enum.

Variants

NeverDialable

Never a destination: reserved, documentation, loopback, link-local, multicast, unspecified, benchmarking, discard-only, IETF-assignments, or port 0.

PrivateScope

Dialable only from inside the same site or carrier region: RFC 1918, RFC 6598 CGNAT, IPv6 ULA. A true reading of the node’s position, and never something to advertise to strangers.

GlobalUnicast

Everything else: an address a stranger on the open internet could route to.
