Latest: wg-quick: darwin: properly parse netstat -nr output · 6 May 2026 - Looking at the source [1], it appears that the interface is always the 4th argument, regardless of the family: C1. if (fam != old_fam) // FALSE P1. p_sockaddr(params, &addr.u_sa, &mask.u_sa, rtm->rtm_flags, WID_DST(addr.u_sa.sa_family)); P2. p_sockaddr(params, rti_info[RTAX_GATEWAY], NULL, RTF_HOST, WID_GW(addr.u_sa.sa_family)); C2. if (params->lflag && (rtm->rtm_addrs & RTA_IFA)) // FALSE P3. p_flags(rtm->rtm_flags, "%-10.10s "); C3. if (params->lflag) // FALSE P4. printf("%*.*s", WID_IF(addr.u_sa.sa_family), WID_IF(addr.u_sa.sa_family), ifname); Because C1, C2, and C3 evaluate to false, interface is always in the 4th argument.
