 - When binding to ::, slipstream attempts to enable dual-stack (IPV6_V6ONLY=0); if your OS disallows it, IPv4 DNS clients require sysctl changes or binding to an IPv4 address.
 - With --fallback enabled, peers that have recently sent DNS stay DNS-only; while active they switch to fallback only after 16 consecutive non-DNS packets to avoid diverting DNS on stray traffic. DNS-only classification expires after an idle timeout without DNS traffic.
