dns error with eww in emacs-25?

[H. Dieter Wilhelm]

Hello,

I'm not sure if this is an eww thing or something strange with my German
dsl provider and network setup. Anyway, I'm not seeing it with Chromium
nor Iceweasel.

Please try M-x eww (with emacs-25 -Q)

duenenhof-wilhelm.de

and then try the link called "Pfauenbilder", instead of the page
peacock.html it appears:

http://navigationshilfe1.t-online.de/dnserror?url=http://peacock.html/

Do you have a hunch what is going on?

Thanks
        Dieter
