Emacs 24.5.1, tramp 2.2.11-24.5
The following code stuck with some DNS settings
>>> file: tramp-loaddefs.el
(defvar tramp-ssh-controlmaster-options
...
(call-process "ssh" nil t nil "-o" "ControlPath=%C" "host.does.not.exist")
...)
<<<
`ssh -o ControlPath=%C host.does.not.exist` stuck instead of going error quickly with DNS from my ISP (both home and workplace).

It is a similar bug report like bug#20015. Solved in Emacs 25 (the git
version), using 0.0.0.1 as not existing host. This avoids problems with
improper DNS settings.
Best regards, Michael.
