Thank you for all the answers.
It seems that waiting a day or so solved the problem, and now ssh doesn't
ask for tweenex password and act like a pass thru, as documented.
One explanation why we see 2 adresses might be because the first one is the
proxy/pass thru server, and the second one the host :
ssh -v twenex at
sdf.org

I can connect to that just fine with the standard OpenSSH client:
abuse at panda:~$ ssh twenex at
sdf.org

You don't need a password, at least not for the ssh session
% ssh -v twenex at
sdf.org

I wonder why I get a different IP address?
Interesting. I get the same address as you do. I double checked with
some other DNS servers -- 8.8.8.8 is an easy one to remember and reliably
reachable. They all show the .16 address.
But I can connect just fine, so it seems that you have a connectivity
issue somewhere on the path. Traceroute to the rescue?
