I stand corrected, it seems to be the DNS server of Windows, see


I have no idea whether Windows DNS servers are widespread enough for
this to cause problems. There is another good explaination in the
mailing list archive


and then there apparently was a cosmetical bug in glibc, see for example
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=305714 . I remember
having those too about a year ago on my Debian box when I experimented
with a faked ip6.int zone with the appropriate DNAME record loaded into
my resolvers.

IMHO decent support for DNAME would be great in general, but in this
particular case I would vote for ripping ip6.int completely instead of
replacing it with the appropriate DNAME. Products still using it have to
be fixed.
