[SNIPPED DEMO]
I did read the entire text of your reported problem. As I usually do, I
attempted to duplicate your problem so that I could confirm that it has
been observed on other machines as well as yours. Since I was unable to
duplicate your problem, I remembered that there had been some changes
in ipv4 when Alexy started working upon it. One of the observed problems
was that some of the network startup files became incompatible. Therefore
I offered some advice.
Here is a session showing that your problem does not occur on this machine
which is running the latest kernel.
For this test, an empty /etc/hosts file was substituted and my nameserver
was removed from /etc/resolv.conf. This makes certain that the machine
does not know any IP addresses.

Notice that there were not any "authorization" problems after the
connection either.
