Bug#457472: openssh-client: ssh resolves some hosts to 1.0.0.0



Package: openssh-client
Version: 1:4.6p1-7
Severity: normal

ssh resolves some hosts to 1.0.0.0. For instance, with the -v option,
I get:

debug1: Connecting to ssh.ens-lyon.fr [1.0.0.0] port 22.

debug1: Connecting to login.medicis.polytechnique.fr [1.0.0.0] port 22.

However, if I first try some other program that does a connection to
the host, e.g. "host <host>", "ping <host>" or "lynx http://<host>/",
then ssh resolves the host correctly (for some time). I suppose that
since other programs don't have any problem, ssh is doing something
wrong.

I've just upgraded to the latest version (unstable), but this didn't
change anything. Note that not all hosts are affected, and this is
not the name server I usually use.

I've attached the output of strace.
