Package: libc6 Version: 2.3.6.ds1-9 Severity: important Adding 'options inet6' in /etc/resolv.conf will cause many programs to crash or misbehave. The documentation currently contains (reformated):
inet6 sets RES_USE_INET6 in _res.options. This has the effect of trying a AAAA query before an A query inside the gethostbyname() function, and of mapping IPv4 responses in IPv6 ``tunnelled form'' if no AAAA records are found but an A record set exists. A *big* warning should be given that setting this flag will cause programs to behave strangely, as they will get back an AAAA record and not the expected A record Additionally one could consider to remove this feature as 'tunneled forms', with which most likely ::a.b.c.d or ::ffff:a.b.c.d are meant are deprecated by the IETF as they only cause issues, for instance like these. For instance a 2.6.x kernel will report the following when doing a IPv4 traceroute (pkg: traceroute-nanog 6.3.10-2): "traceroute forgot to set AF_INET in raw sendmsg. Fix it!" Also SpamAssassin (3.1.7-1) will segfault when this option is used. Separate bugs will be failed against these packages, referencing this bug.
