Scoped down from the original plan: traceroute and --path-diversity's v6 legs are deferred as a documented follow-up, since extending the trace cascade to a second address family is real additional work that doesn't share the trick that made latency cheap. Latency alone captures the core value (a tunneled or poorly-peered IPv6 path is otherwise invisible to tools that only report whichever stack the OS picked) at a fraction of the risk. Turns out no family-detection code was needed at all. icmp_win's ping_samples_win() calls the IPv4-only socket.gethostbyname(), which raises on a v6 literal - already caught by ping_host()'s existing bare except-fallback to TCP, which handles v6 fine via asyncio.open_connection. icmplib handles v6 natively on Linux/macOS. So v6 hosts ride the existing ping_fanout() completely unmodified, tagged with a "<label>-v6" PingResult label instead of a parallel report section - exporter, metrics.py and compare.py needed zero changes since they already key everything off label. New probing.reference_hosts_v6/probing.ipv6 (auto/on/off) config, --ipv6/--no-ipv6 override, interpret.dual_family_findings() for net.ipv6_unreachable and latency.v6_much_slower. Live-tested with --ipv6 forced on a v6-unreachable host: every row fell back to method=tcp with 100% loss as expected. Caught and fixed a wording bug in the same pass - the unreachable finding said "on this dual-stack connection" unconditionally, which is wrong when --ipv6 forces the check on a host that isn't actually dual-stack.
