Perl itself isn't really dual-stack friendly (built-in modules only
do IPv4, you need to install "Socket6" and explicitely use IO::Socket::INET6
to get dual-stack sockets).
The DNS probe in smokeping suffers from the same thing, you can't test
IPv6 servers with it either.
It *should* be fairly easy to fix, though (for AnotherDNS, it's just
replacing one "INET" with "INET6" in the .pm)...
have you enabled IPv6 on something today...?
