Coding error in /usr/src/contrib/bind/bin/dig/dig.c: static void reverse6(char *domain, struct in6_addr *in6) { sprintf(domain, "%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.%x.ip6.arpa", in6->s6_addr[15] & 0x0f, (in6->s6_addr[15] >> 4) & 0x0f, in6->s6_addr[14] & 0x0f, (in6->s6_addr[14] >> 4) & 0x0f, in6->s6_addr[13] & 0x0f, (in6->s6_addr[13] >> 4) & 0x0f, in6->s6_addr[12] & 0x0f, (in6->s6_addr[12] >> 4) & 0x0f, in6->s6_addr[11] & 0x0f, (in6->s6_addr[11] >> 4) & 0x0f, in6->s6_addr[10] & 0x0f, (in6->s6_addr[10] >> 4) & 0x0f, in6->s6_addr[9] & 0x0f, (in6->s6_addr[9] >> 4) & 0x0f, in6->s6_addr[8] & 0x0f, (in6->s6_addr[8] >> 4) & 0x0f, in6->s6_addr[7] & 0x0f, (in6->s6_addr[7] >> 4) & 0x0f, in6->s6_addr[6] & 0x0f, (in6->s6_addr[6] >> 4) & 0x0f, in6->s6_addr[5] & 0x0f, (in6->s6_addr[5] >> 4) & 0x0f, in6->s6_addr[4] & 0x0f, (in6->s6_addr[4] >> 4) & 0x0f, in6->s6_addr[6] & 0x0f, (in6->s6_addr[3] >> 4) & 0x0f, in6->s6_addr[2] & 0x0f, (in6->s6_addr[2] >> 4) & 0x0f, in6->s6_addr[1] & 0x0f, (in6->s6_addr[1] >> 4) & 0x0f, in6->s6_addr[0] & 0x0f, (in6->s6_addr[0] >> 4) & 0x0f); } dig doesn't work with -x option and IPv6 aadresses. Fix: Change line in6->s6_addr[6] & 0x0f, (in6->s6_addr[3] >> 4) & 0x0f, into in6->s6_addr[3] & 0x0f, (in6->s6_addr[3] >> 4) & 0x0f, Report the bug to ISC, too, as it is still in the latest BIND 8 release.
